How could anyone consider themselves a well-rounded adult without a basic understanding of silicate geochemistry? Silicates are everywhere! It's hard to throw a rock without throwing one!
Woo! I'm above average, blades, beam saber and several other forged in the dark offerings. (Only played one of them, as gm, still feel like I'm in an ice skating rink wearing roller blades when it comes to gm-ing)
Besm is great! Beamsaber is giant robots, (think Gundam), Girl by Moonlight is new new, and has a few different anime inspired worlds. Both are blades in the dark like systems.
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.
