I only know a couple. Unless you count the world of darkness games as a lot of games, but I don't. But also unknown armies and don't rest your head. And exalted, but I don't know it well. And gurps, but I only played it once. And fate, of course. And Shadowrun I know of but never played. Still want to do Shadowrun in Fate. And then I've skimmed a bunch of d20 stuff, but if I never read another "roll 1d20 and you have six stats" that's probably okay.
