Currently playing with the local folks: D&D 3.5 (Oathbound, me as the DM), D&D 3.0 (homebrew) and a Swedish cyberpunk/post-apocalyptic game called Mutant (the 1989 version, for those who know about the game). I'm considering dropping Oathbound after this adventure/mini-campaign is finished, and do Eberron instead.
I'm also in two campaigns online: D&D 3.5 (Forgotten Realms) and d20 Modern (Urban Arcana). These run every other week.
