The Generic Universal Role Playing System (GURPS) is a flexible tabletop role-playing game system developed by Steve Jackson Games. Unlike earlier genre-specific games, GURPS was designed from its inception in 1986 to accommodate any setting or story through a unified core mechanic. Players create characters using a point-based system, allocating points to four primary attributes: Strength, Dexterity, Intelligence, and Health. These attributes, along with a wide array of advantages, disadvantages, and skills, allow for highly customized characters. Gameplay typically involves a Game Master adjudicating rules and a world, while players control their characters. Most actions are resolved by rolling three six-sided dice (3d6) against a target number, often related to a character's skill.

GURPS's adaptability is further enhanced by a comprehensive library of over a hundred supplemental books, offering detailed rules and settings for diverse genres. This modular approach allows the system to be played with varying levels of complexity. The system has received critical acclaim, including an Origins Award and induction into the Origins Hall of Fame. Its development has roots in earlier works by Steve Jackson, such as the microgames Melee and Wizard, and the concepts of a point-buy system for character creation were present in earlier designs.

GURPS utilizes a point-based system for character creation, allowing players to define their characters by spending points on attributes, advantages, disadvantages, and skills. The four fundamental attributes are Strength (physical power), Dexterity (agility and coordination), Intelligence (mental capacity), and Health (stamina and vitality). Each attribute is rated on a numerical scale, with 10 representing average human ability. Players can increase or decrease these scores using character points, with scores below average granting points for other customizations. This system allows for a wide spectrum of character concepts, from the mundane to the superhuman. Secondary characteristics like Hit Points, Will, Perception, and Fatigue Points are derived from these primary attributes, further defining a character's capabilities.

A key design principle of GURPS is its universal applicability across virtually any genre or setting. This contrasts with many role-playing games of the past, which were often tied to specific genres like fantasy or science fiction. GURPS achieves this versatility through its core ruleset, which can be expanded and modified using a vast array of supplemental books. These supplements provide detailed rules, settings, and genre-specific information, allowing the system to be tailored to individual needs. This modularity enables GURPS to accommodate diverse playstyles, from highly detailed simulations to more narrative-driven experiences, making it a robust framework for countless gaming possibilities.

The development of GURPS was influenced by earlier role-playing games and Steve Jackson's own previous designs. Prior to GURPS, many games had self-contained, genre-specific rulesets that were often incompatible. Jackson's earlier microgames, Melee and Wizard, along with The Fantasy Trip, laid groundwork for GURPS's core concepts, including attribute scores and a point-buy character creation system, which was also seen in systems like the Hero System. The initial GURPS core rules were published in 1986, with subsequent editions refining the system, notably the Fourth Edition released in 2004 which aimed to streamline gameplay and character creation.
