So, first... I'm sorry. I was in a bitchy mood earlier, for no good reason.
To try to be a useful participant in this conversation...
I play a lot of games. I play a ton of Shadowrun, for example, mostly second or third edition. I still play Original/20th World of Darkness games. I play a lot of Call of Cthulhu, Delta Green, The Laundry Files... All sort of the same thing, I suppose. Sometimes I play Eclipse Phase, or Jovian Chronicles, or Rifts, or...
Well, the point is, I play a ton of games that aren't even remotely D&D.
When I'm in the mood for "D&D", in terms of name-brand D&D product, I usually play 2nd Edition. I also get my Fantasy Fix from Harnmaster, Warhammer Fantasy, or even occasionally Pathfinder. Sometimes I play OSR games; I'm partial to OSE, but I've played others.
My homebrew Fantasy campaign+system, you know, that personal heartbreaker project that most GMs have and have been tweaking and growing for many years? It started with 2E D&D, but I've blended in some elements from Hackmaster, Harnmaster, WFRP, and some of my own ideas.
