I've played Toon, but its been years...I might still have the game entombed in a box in the basement somewhere.

I'm mainly a D&D guy, though that may change in the future, with the 4th edition of the game rapidly approaching. I haven't seen any changes that are making me excited for the new version, or willing to shell out the huge wads of cash it'll take to get the books.

As for other games I own/play: Shadowrun, Cyberpunk, Gamma World, Rifts, TMNT, Palladium RPG, among others...
