I've played tonnes of table top rpgs over the years: D&D, AD&D (1st and 2nd Ed only), Gamma World, Star Frontiers, Boot Hill, Heroes Unlimited, Macross, Villains & Vigilantes, Call of Cthulu, Runequest ... and more that I can't think of at the moment. (This is being typed pre-coffee PDT_008 )
These days I'm more into playing JRPGs for Playstation/XBOX and Warhammer 40,000.
