When I saw this poll, I thought "well, the answer is going to be 5e overwhelmingly, because that's what most people talk about around here." And lo and behold, that seems to be the case. I am a bit surprised at the small number of 2e folks given the love it seems to get in comments, but that may be because of the lack of widely played 2e clones - the retroclone folks have done a lot with B/X and with 1e AD&D, but I would guess that folks answering 2e I would bet are actually playing 2e and not using a clone of some kind. (it would be interesting to see a version of this question where the clones were specifically broken out to see who is still playing straight-up with the old rulebooks and who is using OSRIC or Labyrinth Lord or whatever).
