In no real order these are the Seven games I have played the most in my life, or at least as far as I can tell...
Teenage Mutant Ninja Turtles & Other Strangeness: We played this game like nobodies business, I must have gone over and over it hundreds of times, we loved it.
Heroes Unlimited: This was our go to game as far as Super heroes, everybody hated my villains we had a blast!
Rifts: I loved this game, the world was over the top, it was utter wazoo and munckin to the max. This pretty much wraps up the Palladium games we loved, although Robotech was played, nothing like the three so far listed though.
Shadowrun: I played this more than ran it, it never seemed to work right for me. I love the game and the world.
Call of Cthulhu: Playing this game scared me, I ran it more than played and we always had a good time, it was my introduction to all things Lovecraft also!
AD&D 2e: More than any other edition this was it, and although I don't play this edition anymore I still have many fond memories of the games we played.
BECMI: Here was the version I played the most of during my Military life, the RC was easy to carry around from place to place and the Shop on base in Korea carried nothing but BECMI stuff.
