Tabletop Roleplaying Games

Released in 2014 by Chaosium, Call of Cthulhu 7th Edition is the latest version of the cult-classic cosmic eldritch horror role-playing system originally launched in 1981. The story is based off of the  literary works of H.P. Lovecraft and lovecraftian works. Instead of setting the players up as heroes, the characters are regular investigators who are exploring cults, forbidden knowledge and various eldritch-cosmic entitites and threats. Description Occupations in the game for the characters include academics, reporters, and private investigators. The gameplay loop revolves around uncovering information, analyzing clues, and evading dangers. As the supernatural elements in the game are considered more powerful than the investigators, they have are not expected to actually confront most of the threats head on. Instead they usually have to resort to avoiding or escaping any situation that may arise. Combat is lethal and usually leads to characters getting permanently killed or pushed to insanity (which eventually is the same).  System Overview & Key Features Percentile Framework (d100) Every action is resolved by rolling two ten-sided (d10) dice to get a result from 1 to 100. If you roll is equal to or under your skill rating, the action is deemed a success. This approach simplifies the mechanical process of the game, as there are no complex tables to keep track of and compare to decypher whether it is a success or failure. Pushed Rolls If a character fails a skill check, they may attempt to "push" the roll, allowing for a second attempt. This requires the player to come up with a new, more desperate approach to performing the task. If this subsequent pushed roll also fails, the Keeper describes a severe and immediate negative consequence. Sanity and Madness A core mechanic of the system is the tracking of mental stability. Investigators lose points from their Sanity gauge when exposed to anomalous creatures or disturbing truths. Drops in Sanity result in the character experiencing temporary or permanent forms of madness, which can manifest as new phobias, delusions, or a temporary loss of player agency over the character. Bonus and Penalty Dice To account for situational advantages or disadvantages, the game employs a system of bonus and penalty dice. If a character possesses a distinct advantage when performing a task, an extra d10 is rolled and taking the higher result. A disadvantage means rolling an extra d10 and taking the lower result. Combat Lethality Physical altercations are inherently dangerous by design. Investigators possess limited hit points, and the damage output of both conventional firearms and anomalous entities is high. Recovery mechanics are slow, simulating realistic healing times. This structural lethality serves to discourage combat and incentivize stealth and investigation. Expendable Luck Players can spend points from their character's Luck pool to retroactively lower a dice roll. The points are subtracted on a one-to-one basis until the dice result qualifies as a success. This ensures that the Luck pool is a limited resource which should be used and utilized in the most critical situations.

Basic Roleplaying is the venerable "D100" engine that has powered Chaosium’s greatest hits for over four decades. Originally appearing as a slim booklet in 1980, it was most recently revitalized as the Basic Roleplaying: Universal Game Engine in 2023. In 2026, it stands as one of the industry's most important open-source platforms, released under the ORC License, allowing independent creators to build and sell their own games using its legendary, time-tested mechanics. Description BRP is a "genre-neutral" toolkit that discards character levels and rigid classes in favor of a pure skill-based system. Whether you are playing a Bronze Age warrior, a 1920s detective, or a futuristic mech pilot, the core experience remains the same: your character is defined by what they can do. Because it uses percentages (e.g., "I have a 65% chance to climb this wall"), it is widely considered the most intuitive and "transparent" RPG system for new players to understand at a glance. System Overview & Key Features The Universal D100 Engine Every action is resolved by rolling two ten-sided (d10) dice to get a result from 1 to 100. If you roll is equal to or under your skill rating, the action is deemed a success. This approach simplifies the mechanical process of the game, as there are no complex tables to keep track of and compare to decypher whether it is a success or failure. Organic Character Growth There is no "Experience Points" system in the traditional sense. Instead, when you succeed in using a skill, you mark a "Skill Check" on your character sheet. At certain stops in the game/story, the player rolls to see if the character improves in those skills, meaning your character evolves based specifically on the actions they performed (and succeeded at) during the game. Modular Rule Design The Universal Game Engine is designed with variations and systems to choose from. GMs can choose whether they prefer to just use "Hit Points" or add a more detailed wound system with "Hit Locations" for more realistic tactical consequences. Systems for Magic, Sorcery, Mutations, or Superpowers (depending on the setting) can be added, instead of being baked in the core mechanics, ensuring the mechanics always fit the theme of the game. Deadly and Tactical Combat BRP combat is grounded and dangerous. Unlike high-fantasy games where adventurers have a vast health pool, a single strike of a sword or bullet in BRP can be fatal. This encourages players to think creatively and use mechanics and terrain to their advantage. Talking their way out of situations is often seen as more reasonable (and survivable), than just treating every conflict as a forced combat situation. The ORC License Revolution By introducing to the Open RPG Creative (ORC) license, BRP started a wave of third-party "Powered by BRP". This has expanded the system into new genres like Cyberpunk, Wuxia, and Cozy Fantasy, all supported by a single, unified ruleset and system, compatible with most themes. Compatibility with "The Big Three" Because the core mechanics have remained the same since the beginning, a monster or spell from a 1980s supplement is almost always compatible with the modern 2026 engine. This gives GMs access to one of the largest libraries of pre-written adventures in tabletop gaming, spanning Call of Cthulhu, RuneQuest, and Pendragon.

King Arthur Pendragon is a tabletop roleplaying game of Arthurian chivalry, tragedy, and multi-generational legacy, originally designed by Greg Stafford and first published by Chaosium in 1985. It's one of the hobby's oldest continuously-revised games, having passed through five earlier editions and several publishers (including Green Ronin's Arthaus imprint and Nocturnal Media) before returning to Chaosium, who released the 6th Edition in April 2024.  Stafford completed the design draft for this edition before his death in 2018, with longtime Pendragon line editor David Larkins overseeing it to print - a fact the game's own promotional copy leans into, framing it as the culmination of nearly forty years of Stafford's design thinking on the setting. Description Players take on knights of Arthur's Britain, sworn to a lord and bound by a code of chivalry the game asks characters - and players - to genuinely wrestle with rather than simply declare. The Game Master (GM) runs a campaign built to span decades of in-world time: between adventures, a Winter Phase resolves a knight's marriage, estate management, aging, and family events, and campaigns are explicitly designed to carry a player from their original knight's prime through old age and into playing that knight's own heir.  The game asks a lot of a table willing to commit to it - character death by old age is expected, not a failure state, and a knight's personal flaws are written onto the character sheet where they can force bad decisions at the worst possible moment. In exchange, it delivers something few other RPGs attempt: a genuinely generational campaign where a table can watch the consequences of one knight's choices land on their grandchild decades later.

RuneQuest: Roleplaying in Glorantha (RQG) is a mythic fantasy tabletop roleplaying game set in Greg Stafford's Bronze Age world of Glorantha, published by Chaosium in 2018. It is credited to Jeff Richard, Greg Stafford, Jason Durall, and Steve Perrin, with a long list of contributors from earlier editions. RuneQuest first appeared from Chaosium in 1978 and has passed through several publishers since, including Avalon Hill (third edition, 1984), Mongoose Publishing (2006), and The Design Mechanism (sixth edition, 2012, later continued as Mythras). RQG is the Chaosium-published line that returned to Glorantha, and it is a different game from those later editions. The system directly evolved from the original RuneQuest (1978), whose percentile core was later distilled into Chaosium's Basic Role-Playing, the engine behind Call of Cthulhu and Pendragon. Description Players take on adventurers from the clans and tribes of Dragon Pass, from homelands such as Sartar, Prax, the Grazelands, Esrolia, and Tarsh, in a world where gods are neighbors and myths are history.  The Game Master (GM) runs a setting built around cults, clan feuds, and the Hero Wars gathering on the horizon, and characters belong to a family, a homeland, and a religion before they ever pick up a sword. The game asks a table to take that seriously: combat is lethal, shields shatter and limbs get disabled, and there are no luck points to buy a character out of a bad round. In return it offers one of the hobby's most fully realized worlds, where a character's gods, ancestors, and passions shape play as much as their weapon skill.

7th Sea is a swashbuckling fantasy tabletop roleplaying game of piracy, duels and intrigue in the world of Théah, created by Jennifer Wick and John Wick, with Kevin Wilson co-writing, and published by Alderac Entertainment Group (AEG) in April 1999. It won the Origins Award for Best Roleplaying Game of 1999, presented in 2000, and was fairly well received. The game originally used a d10 roll-and-keep system, in which players roll a pool of ten-sided dice (d10) and keep only some of them. It also inspired a collectible card game that was discontinued in 2005. In 2004 AEG moved the line to the d20 System and renamed it Swashbuckling Adventures, a change many fans of the original rules disliked. Later books supported both systems. The first edition later went out of print, and volunteer writers have since released e-books and adventures for it. Chaosium acquired 7th Sea and its rights in 2019. The second edition of the game was released in 2016 as 7th Sea Second Edition, a new system from John Wick Presents. Description Players take on heroes in Théah, a fantasy version of 17th-century Europe whose nations are exaggerated versions of real kingdoms. The setting draws on 1600s European literature, with sorcery playing a major role and a dominant religion that resembles gnostic Christianity, complete with a parallel to the Spanish Inquisition. The Game Master (GM) runs adventures of sea voyages, court intrigue and sword fights. The game asks a table to embrace the swashbuckling genre and the era's romance, and to tolerate a 1990s rulebook that is now out of print. Anyone picking it up should check which system a given book is written for, since AEG published for both the original roll-and-keep rules and the d20 System.

7th Sea Second Edition is a swashbuckling tabletop roleplaying game of high adventure, intrigue and romance in Théah, a magical continent inspired by 17th-century Europe, published by John Wick Presents in 2016. It was written by John Wick, Mike Curry, Rob Justice, Mark Diaz Truman and Jesse Heinig. AEG transferred the publication rights to John Wick Presents in 2015, and the second edition was crowdfunded on Kickstarter in March 2016 with the core rules appearing in June 2016. It won six ENNIE Awards in 2017. In 2019 Chaosium acquired 7th Sea and its rights, with John Wick joining Chaosium as creative director, and the line is now sold through Chaosium's store. Later books added the Crescent Empire, the New World, Ifri and the Woven Land. The system directly replaced 7th Sea First Edition (1999), although it is a new set of rules and not a revision of the original. Description Players take on heroes who uncover global conspiracies, explore the ruins of a vanished race and protect the rightful rulers of Théah from villains. The Game Master (GM) runs the story and the villains, and the game's structure, built around personal Stories, suits campaigns more than one-shots. A reviewer described it as a narrative indie game dressed up as a traditional one. The game asks a table to be comfortable with negotiating the fiction and with a GM who plans scenes in advance. The setting chapter runs to 96 pages in a hardback of about 300 pages, and players may expect more rules than the game actually uses.
