Well, I think that it is safe to say that I have played at least one game of nearly half of every single RPG system out there... Games I've played on a regular basis, now or in the past: AD&D (1st, 2nd, and 3rd editions) BESM (Big Eyes Small Mouth) Palladium (RIFTS, Ninjas and Superspies, Robotech, etc) TORG Seventh Sea Legend of the Five Rings (Original and d20 version) DC Heroes RPG (system now owned by Pulsar and released as "Blood of Heroes") The old Marvel Superheroes RPG by TSR Star Trek: TRPG Mekton Mechwarrior Warhammer Fantasy Roleplay Rolemaster Shadowrun Cyberpunk Champions (4th ed) Fuzion (an attempt by R Talsorion to combine Champions with the Interlok system [Mekton and Cyberpunk]) And probably a lot more that I'm not thinking of right now... and I have heard of nearly every single RPG out there. Even done work carving figures for Team Frog...
