I'm a member of a local D&D Meetup which is not very active, unfortunately. There was a poll posted on February 12th, asking "If you are a DM, What Edition of D&D do you DM?"
Out of 56 members, only 12 have responded.
3 members would prefer to play
9 members prefer to DM.
Out of the 9 DMs, 4 of them DM 3.0/3.5.D&D/Pathfinder, 4 DM 4th Edition and 1 DM's (which is me!)a Retro-clone.
How sad is that?
It would be interesting if the re-release of the AD&D books in April will have an impact on getting new people to play the older versions of the game.
