Played a hell of a lot of 1st ed. Gave 2nd a miss and resumed playing when 3rd ed came out. Played and run my own 3.5 campaign by table top. When 4th ed came out played a few sessions which didn't excite me so I started running a 1st ed game. DMed the Saltmarsh adventure Path then onto the Temple of Elemental Evil and finally the Scourge of the Slave Lords. O late have been playing Pathfinder and the every so often a 1st ed game, either on google hang outs or here on Roll 20.
I have also played 1st ed Star Wars, Twightlight 2000, Cyberpunk,, Nightlife (man i loved that game and wouldn't mind Gming it), Cthulhu and numerous other games.
