"The Generic Universal RolePlaying System, or GURPS, is a tabletop role-playing game system designed to allow for play in any game setting. It was created by Steve Jackson Games and first published in 1986 at a time when most such systems were story- or genre-specific.
"Players control their in-game characters verbally and the success of their actions are determined by the skill of their character, the difficulty of the action, and the rolling of dice. Characters earn points during play which are used to gain greater abilities. Gaming sessions are story-told and run by "Game Masters" (often referred to as simply: "GMs").
"GURPS won the Origins Award for Best Roleplaying Rules of 1988, and in 2000 it was inducted into the Origins Hall of Fame. Many of its expansions have also won awards."
For style, I really have to give (GURPS Fourth Edition) a 5 out of 5. I really can't imagine how you could make a GURPS rulebook more stylish. It's really a beauty - I have to say that stylistically, it's the most beautiful mainstream RPG that I own."
"I think (GURPS) has the most appeal to people who want complete freedom in their characters and games, whilst not minding the complexity. It also is designed to handle crossed settings very well, so if you’re wanting game with parallel universes, time travelling, or something like that, then GURPS will work quite well."
"The Dev Team Thinks of Everything: GURPS sourcebooks are notorious for how complete they are, in many cases the setting and research in them is used by gamers using other systems because of how well written they tend to be. In something of a Crowning Moment Of Awesome, the third edition Bio-Tech book, published in 2002, was noted to be as up to date on it real world Biotech as some college textbooks on the issue, by a variety of professionals in the field. And in 1997 the Camelot sourcebook actually ended up on the recommended reading list for a course in Arthurian Literature at Indiana University."
