Well, for over a year now I've been occasionally (not too persistently, but from time to time) trying to get the guys around here to try out the D&D Next playtest stuff. Mostly because I'm curious about what they're doing with it, not so much because I think I'll buy it. But who knows, I might...
Anyway, I finally am getting the chance. It may be a while before I can pass judgement, though, as the game will be a play-by-post game on RPOL.net. But it's D&D Next, the Ghosts of Dragonspear Castle module, and the DM started out with BECMI (same as me) and mostly played that back in the day, although from comments he's made he is/was big into 4E.
So far, character creation wasn't too difficult. Of course, I was rolling up a Fighter, so that's usually a little simpler than some other classes. The process was fairly painless. While every class in Next has a boat-load of special abilities that they gain as they level up, the removal of feats speeds things up quite a bit, and simplification of skills (at least in the most recent packet) into "fields of lore" also speeds things up compared to 3E/Pathfinder/4E. Still not as simple as BX, but not too time consuming. Even considering the time I spent debating whether to play Fighter or Rogue didn't take that long.
So, eventually, I may have something more to say about Next. But due to the slow pace of PbP games, don't hold your breath.
