Here we can discuss the "Classic" product line, or those versions of D&D that didn't follow the AD&D fork when the line split. This would include B/X (1981), BECMI (1983), Rules Cyclopedia (1991), and the games later marketed as "the Classic D&D game." (1994)
Topic specific to the 5E version of D&D (a.k.a. "D&D Next") which has been playtested for a year or more and finally released summer 2014. I've moved this sub-board into a regular board for a while in anticipation that there might be a lot of chatter about 5E.
