The d20 System is a role-playing game system published in 2000 by Wizards of the Coast , originally developed for the 3rd edition of Dungeons & Dragons . The system is named after the 20-sided dice which are central to the core mechanics of many actions in the game.
58-613: Much of the d20 System was released as the System Reference Document (SRD) under the Open Game License (OGL) as Open Game Content (OGC), which allows commercial and non-commercial publishers to release modifications or supplements to the system without paying for the use of the system's associated intellectual property, which is owned by Wizards of the Coast. The original impetus for the open licensing of
116-1069: A d20 mini-RPG found in Polyhedron Magazine issue #149 (also known as Dungeon Magazine issue #90). Polyhedron #161 (also known as Dungeon #102 ) contained a d20 Modern "update" of the Pulp Heroes mini-game. The setting allows one to play games that take place during the famous Pulp Era of literature, filled with ancient dinosaurs , power-hungry gangsters , vengeful vigilantes , amazing superheroes , evil Nazis , bizarre inventions , mystical psionics , hard-boiled detectives , trained martial artists , curious explorers , eldritch aliens , and various other fantastic people, places, and things. The worlds of H. P. Lovecraft 's Cthulhu Mythos and Sir Arthur Conan Doyle 's The Lost World , and famous individuals like Jules Verne , H. G. Wells , Doc Savage , Tarzan , and Indiana Jones serve as perfect examples of this era. Many elements of Pulp Heroes were adapted into
174-503: A System Reference Document ( SRD ) is a reference for a role-playing game 's mechanics licensed under a public copyright license to allow other publishers to make material compatible with that game. In 2000, Wizards of the Coast pioneered this by releasing a SRD for Dungeons & Dragons 3rd edition under their Open Game License (OGL). Dicebreaker described a SRD as a "handy guide on how to use, hack and implement an existing game system for your own purposes". The first SRD
232-421: A Smart Investigator and Field Scientist (one basic, two advanced). There are no limitations in the rule set as to how many classes a hero may have, but two or three are typical. Dividing experience and character development between too many classes results in breadth at the cost of having weaker abilities in each class. Some gamemasters (GMs) may set restrictions on certain advanced classes in their campaign. E.g.,
290-449: A character spends one action point, the character receives a small boost in his or her skill checks, ability checks, level checks, or saving throws. There's a bit of restriction when and where to use them. As the character spends these points, they're very limited. However, through level advancement, he or she replenishes spent action points. In order to fit the d20 Modern setting, some skills and items are reworded and rebalanced, and both
348-565: A compatible product. The 5th edition of D&D was released in 2014. A new OGL-licensed SRD based on 5th edition was released in January 2016, and updated to version 5.1 in May 2016. In January 2023, Wizards of the Coast announced that the full D&D System Reference Document 5.1 (SRD 5.1) would be released under the CC-BY-4.0 license. Some other game systems, such as FATE ,
406-433: A distinctive logo to help consumers identify these products. This was known as the d20 System Trademark License (d20STL). The d20STL required publishers to exclude character-creation and advancement rules, apply certain notices, and adhere to an acceptable content policy. D20STL products were also required to clearly state that they require the core books from Wizards of the Coast for use. All d20STL products also had to use
464-405: A future divested from the weight of D&D. [...] SRDs, or whatever their next form might look like, may provide fledgling artists waystones through an open field instead of fence posts around private property". D20 Modern d20 Modern is a modern fantasy role-playing game system designed by Bill Slavicsek , Jeff Grubb , Rich Redman, and Charles Ryan . The system's core rulebook
522-431: A player character may qualify over time: Advanced classes can be less or more easily achieved depending on the hero's basic class. For instance, a Tough Hero can be an excellent candidate for Bodyguard or Daredevil, but would have more difficulty becoming a Techie or Acolyte. At later levels, the player may choose to multi-class their hero; for example, a Strong and Dedicated Bodyguard (two basic classes, one advanced), or
580-474: A vague approximation which is still plausible in that person's beliefs about reality. (See consensus reality .) For example, an ogre would appear to the average person as a very burly man. The player characters are somehow capable of seeing through this veil, and typically take on responsibility for defending humanity from the monsters. It originally appeared as a d20 mini-game in Polyhedron Magazine issue #150. In this campaign setting, magic (at least in
638-408: A wide variety of genres, but is intended for a modern-day, or in the case of the last of these, a futuristic setting. Ryan Dancey believed that the strength of Dungeons & Dragons came from its gaming community instead of its game system, which supported his belief in an axiom that Skaff Elias promoted known as the "Skaff Effect" which posited that other role-playing game companies increased

#1732786901937696-460: Is consistently used for all action resolution in the d20 System. In prior games in the D&D family, the rules for different actions, such as the first-edition hit tables or the second-edition Advanced Dungeons & Dragons ( AD&D ) " THAC0 " and saving throw mechanics, varied considerably in which dice were used and even whether high numbers or low numbers were preferable. The d20 System
754-515: Is not presented as a universal system in any of its publications or free distributions, unlike game systems like GURPS . Rather, the core system has been presented in a variety of formats that have been adapted by various publishers (both Wizards of the Coast and third-party) to specific settings and genres, much like the Basic Role-Playing system common to early games by veteran role-playing game publisher Chaosium . The rules for
812-609: Is referred to as a hero. All heroes start with a first-level, basic class. Each basic class corresponds to one of the six ability scores in the d20 System . Each basic class has its own set of skills, feats, talents, saves, hit dice, wealth bonus, and so on. A beginning basic hero will become a more specific advanced-class hero at later levels, depending on which abilities a player favors for their character. The six basic classes are: In addition to basic classes, there are also advanced classes. Similar to basic classes but with requirements to fulfill. There are 14 advanced classes for which
870-481: Is similar to Call of Cthulhu d20 meaning that you can get dead real quick. [...] My favorite aspect about the world background is that we're already living about 90% of it. As a GM all you have to do is fill in the last 10%. It's not like building or learning a whole new fantasy world from scratch". Theuar also "particularly liked the Wealth system". Academic Kris Green also highlighted the d20 Modern Wealth system in
928-593: The Pathfinder Roleplaying Game , among others. The 4th edition of D&D , released in 2008, was not licensed under the OGL, but under the more restrictive Game System License . Subsequently, the 4e System Reference Document is quite different. Instead of the full texts of the OGL-licensed rules, the 4e SRD presents only lists of concepts and tables from the 4e rulebooks that may be used in
986-636: The Mongoose Publishing editions of RuneQuest , Traveller , and Zweihänder Grim & Perilous RPG have also released their own mechanics under distinct OGL-licensed "System Reference Documents". Chase Carter, for Polygon in 2022, highlighted that the indie game design scene "has moved toward extremely permissible SRDs and the open plains of collaboration. [...] When SRDs do pop up in indie games, they read more as political statements about art and creation under capitalism". Carter commented that "independent designers are looking toward
1044-586: The United States of America in 1976. The game creates an imaginary cross-country car race, and uses d20 System modern vehicle rules. The vehicle rules that were described in the game were also recommended for use with the previous d20 Modern mini-game preview Shadow Chasers ( Polyhedron #150 ). In Thunderball Rally , the player characters portray one of the crews in the largest, most lucrative, most illegal crosscountry road race in America. Examples of

In response to the sexually explicit Book of Erotic Fantasy (2003) announced by Valar Project for Dungeons & Dragons , Wizards of the Coast changed the d20 license so that publications were required to meet "community standards of decency", prompting Valar to simply remove direct references to Dungeons & Dragons and publish
1160-410: The Coast has been significantly more conservative when adapting the d20 System to a modern setting. d20 Modern retains many elements that other modern and ultramodern games dispense with or modify, such as iterative attacks and hit points. However, d20 Modern uses some aspects of the game that appeared in the d20 Star Wars game. [...] The fundamental difference between the approach to classes and
1218-412: The Coast then-president Peter Adkison . Many give Tweet the bulk of the credit for the basic resolution mechanic, citing similarities to the system behind his game Ars Magica . Tweet, however, stated "The other designers already had a core mechanic similar to the current one when I joined the design team". To resolve an action in the d20 System, a player rolls a 20-sided die and adds modifiers based on

#17327869019371276-418: The OGL alone. When gaming company Valar Project attempted to publish the d20 Book of Erotic Fantasy ( BoEF ), which focused on sexual content, Wizards of the Coast altered the d20 System Trademark License in advance of publication of BoEF by adding a "quality standards" provision that required publishers to comply with "community standards of decency." This subsequently prevented the book's publication under
1334-416: The OGL to make use of d20 System open content. However, products that only use the OGL are not bound by these restrictions; thus publishers were able to use the OGL without using the d20STL, and by including their own character-creation and advancement rules allow them to function as complete standalone games. With the release of the 4th edition of Dungeons & Dragons in 2008, Wizards of the Coast revoked
1392-662: The SRD include detailed descriptions, flavor text, and material Wizards of the Coast considers more specific product identity (such as references to the Greyhawk campaign setting and information on mind flayers ). d20 Modern has its own SRD, called the Modern System Reference Document (MSRD). The MSRD includes material from the d20 Modern Roleplaying Game , Urban Arcana Campaign Setting , d20 Menace Manual , and d20 Future . The MSRD can cover
1450-442: The Wealth bonus. It functions just like any real world currency: income, credit, debit, to deposit or withdraw, purchasing and selling, and so on. It also defines the characters' financial conditions, from being opulent to impoverishment. All characters have their own wealth. Determining wealth at first level, the player rolls a four-sided die two times (2d4), and then adds the results together. The result can be increased by occupation,
1508-563: The Windfall feat, and the Profession skill. Whenever the character advances in level, the player rolls a Profession check. d20 Modern presents three sample campaign settings. These settings, unlike the rest of the book, feature the supernatural. In this setting, evil monsters, usually from one or more parallel dimensions, roam free around the world. However, most people do not see these creatures for what they really are, seeing instead
1566-514: The advanced classes might require more experience points to acquire, or some might not be available until specific objectives have been reached in the game campaign. GMs may also entirely rule out certain classes, e.g. Acolyte and Mage because their spell-casting abilities do not fit the GM's hard sci-fi scenario. One of the interesting additions to the system was the action points. Actions points are used by characters to affect game play greatly. Whenever

Green wrote that "rather than force players to keep detailed records of every purchase a character makes and bank record he accesses, the d20 Modern designers created a single abstract quantity called 'Wealth' that determines how easy it is for a character to acquire equipment and resources. Players roll against
1682-468: The book under the OGL. This event, by highlighting that Wizards of the Coast still held wide discretionary power over what counted as legitimate d20 material, made third-party game writers leery of publishing under the d20 license. Wizards of the Coast released an updated version of Dungeons & Dragons , edition 3.5 at Gen Con 36 in August 2003. Third-party publishers were given little warning regarding
1740-433: The classic Macho Women with Guns (2003, 2005)". In 2022, Jeff Grubb – co-creator of d20 Modern – announced an upcoming role-playing system titled Everyday Heroes which is based on the 5th edition Dungeons & Dragons ruleset via Wizard's Open Game License . Sigfried Trent, one of the lead designers, described the game as merger of "the theme, the setting, the mood, the feeling of d20 Modern " and "the rules,

Dark•Matter: Shades of Grey is a d20 Modern mini-game of conspiratorial suspense presented in Polyhedron Magazine issue #167 (also known as Dungeon Magazine issue #108 ) and then as a stand-alone d20 Modern book, Dark•Matter , in September 2006. It is a remake of the Dark•Matter campaign setting for Alternity . It uses concepts from

1856-481: The core d20 Modern RPG rules and the Urban Arcana and d20 Menace Manual sourcebooks, which are also recommended for use to get the most from the setting. Mecha Crusade was a d20 mini-RPG campaign setting in issue #154 of Polyhedron Magazine ( Dungeon Magazine issue #95). The setting was a take off of anime mecha series, like Mobile Suit Gundam or Macross . Pulp Heroes started as
1914-463: The core books from Wizards of the Coast, and publishers even started to create OGL-based games that were direct competitors to D&D . Because Dungeons & Dragons is the most popular role-playing game in the world, many third-party publishers of the 2000s produced products designed to be compatible with that game and its cousin, d20 Modern. Wizards of the Coast provided a separate license allowing publishers to use some of its trademarked terms and
1972-430: The corresponding D&D classes is that the d20 Modern classes are much more general". Mark Theuar, for the gaming magazine Fictional Reality , wrote that he would "highly recommend this book to anyone wanting to play in a modern day rpg" and that "the interior artwork has sort of a graphic novel feel to it and it works very well for this setting". He highlighted his enjoyment of the section on guns and that "combat
2030-562: The d20 System are defined in the System Reference Document or SRD (two separate SRDs were released, one for D&D 3rd edition and one for edition 3.5), which may be copied freely or even sold. Designed for fantasy-genre games in (usually) a pseudo-medieval setting, the SRD is drawn from the following D&D books: Player's Handbook v3.5, Expanded Psionics Handbook , Dungeon Master's Guide v3.5, Monster Manual v3.5, Deities and Demigods v3.0, Unearthed Arcana , and Epic Level Handbook . Information from these books not in
2088-410: The d20 System involved the economics of producing role-playing games (RPGs). Game supplements suffered far more diminished sales over time than the core books required to play the game. Ryan Dancey , brand manager for Dungeons & Dragons at the time, directed the effort of licensing the new edition of Dungeons & Dragons through the d20 System Trademark , allowing other companies to support
2146-533: The d20 System under a common brand identity. This is distinct from the Open Game License, which simply allows any party to produce works composed of or derivative of designated Open Game Content. The d20 System is a derivative of the third edition Dungeons & Dragons game system. The three primary designers behind the d20 System were Jonathan Tweet , Monte Cook , and Skip Williams ; many others contributed, most notably Richard Baker and Wizards of
2204-432: The d20 license helped create an industry for PDF publishing for role-playing games to fill the demand for d20 products, where electronic delivery presented players with a very quick and inexpensive method to distribute content. Wizards also began using their d20 system beyond just fantasy games, including their own Star Wars Roleplaying Game (2000) and the d20 Modern Roleplaying Game (2002). Wizards developed one of
2262-421: The d20STL. Wizards of the Coast said this was done to protect its d20 System trademark. The Book of Erotic Fantasy was subsequently published without the d20 System trademark under the OGL. Other books subsequently published under similar circumstances include Skirmisher Publishing 's Nuisances , which includes on its cover the disclaimer "Warning: intended for mature readers only." The same round of changes to

Charlie Hall, for Polygon , stated that "back in 2002, d20 Modern helped to breathe life into third edition Dungeons & Dragons , expanding the tabletop role-playing game into a far more contemporary setting — less swords and sorcery, more ninjas and automatic weapons". Shannon Appelcline commented that d20 Modern

Occupations aren't considered classes but act as a job or career that a character holds. He or she may hold multiple occupations, but over time. There are over 19 different occupations and each with its own restrictions, such as age. As well, they open more options when choosing skills and higher Wealth bonus. The 19 occupations are: Academic, Adventurer, Athlete, Blue Collar, Celebrity, Creative, Criminal, Dilettante, Doctor, Emergency Services, Entrepreneur, Investigative, Law Enforcement, Military, Religious, Rural, Student, Technician, and White Collar.

2436-643: The future. Initially there was a boom in the RPG industry caused by its use of the d20 license, with numerous companies publishing their own d20 supplements. Some companies used the d20 system to attempt to boost the sales of their proprietary systems, such as Atlas Games and Chaosium , while many other publishers produced d20 content exclusively, including existing companies such as Alderac Entertainment , Fantasy Flight Games , and White Wolf Publishing , as well as new companies like Goodman Games , Green Ronin , Mongoose Publishing , and Troll Lord Games . The success of

Wizards then extended this development of d20 even further, with the science-fiction game d20 Future (2004) as well as the historical game d20 Past (2005). Wizards ended this line in 2006 by updating their classic campaign setting Dark•Matter for d20 Modern . In d20 Modern , each character

If the result is greater than or equal to a target number (called a Difficulty Class or DC) then the action succeeds. This is called the Core Mechanic. This system
2784-491: The original d20STL, replacing it with a new license specifically for D&D, known as the Game System License . The terms of this license are similar to the d20STL, but there is no associated OGL or Open Content, and the 4th-edition SRD merely lists the items and terms which may be used in licensed products. This did not affect the legal standing of the OGL, and products based on the SRD may still be released under
2842-438: The settings from d20 Modern into the full Urban Arcana Campaign Setting (2003) sourcebook, and further extending the d20 into science-fiction with d20 Future (2004) and into historical settings with d20 Past (2005), then finished up their d20 line in 2006 with the classic Dark•Matter campaign setting. Third-party publishers used these d20 genre books to base their own campaign settings on, such as White Wolf using

Some, however, break that barrier and become aware of the world around them, and help Mages, Acolytes, and other magical characters fight with monsters from another realm. This campaign setting combines aspects of the previous two settings ( Shadow Chasers & Agents of Psi ) and uses
2958-455: The success of the market leader, which at that time was Wizards of the Coast . Dancey also theorized that the proliferation of numerous game systems actually made the role-playing game industry weaker, and these beliefs together led Dancey to the idea to allow other publishers to create their own Dungeons & Dragons supplements. This led to a pair of licenses that Wizards of the Coast released in 2000, before 3rd edition Dungeons & Dragons

Between these two crises, many d20 publishers went out of business or left the field, but most that remained totally abandoned the d20 trademark in favor of publishing under the OGL. Publishers realized that they could publish d20 games successfully without depending upon

But, many other publishers put out large d20 Modern lines. Some of the most notable were Adamant's Thrilling Tales (2005-2007) and Mars (2006-2007) line, Green Ronin 's varied d20 Modern rules and settings, which culminated in Damnation Decade (2006), and Mongoose 's new editions of

That SRD allowed for third-party publishers to freely produce material compatible with D&D . It also formed the basis for independent role-playing games from other publishers, such as Mutants & Masterminds and
3364-499: Was released: the Open Gaming License (OGL) made most of the game mechanics of 3rd edition D&D permanently open and available for use as what was known as system reference documents, while the d20 Trademark License allowed publishers to use the official "d20" mark of their products to show compatibility with those from Wizards of the Coast. Unlike the OGL, the d20 License was written so that Wizards could cancel it in
