I discovered GURPS around 1989 or 90 when I was a young gamer. I've collected books, read books, play a few sessions though surprisingly few for how much I like the game, GM'd a bit more and done some comped play-testing.
It was my very favorite system for many years, the only one I regularly bought anything for.
It stayed at number one only supplanted by its offspring, the Unisystem written by GURPS Voodoo alum C.J Carella .
Unisystem famous for Buffy and All Flesh Must Be Eaten is basically the child of GURPS and World of Darkness, using a simpler system of character generation more akin to WoD but with a strong focus on verisimilitude like GURPS has.
However imagine a hideous world without GURPS or Unisystem would I'd still be gaming?
I'd almost certainly be playing D&D of some kind, I still do , the Fantasy Trip if it existed and I discovered it and likely some kind of system that covered modern fantasy.
I'd also be playing BRP/Call of Cthulhu probably a lot of it. My 1st serious RPG was Runequest 2 and it was and is a great game.
The Return of Planescape? - Curious. There is a brief note on this 'countdown' at Enworld.
