Well, this is the edition to play. Dungeons & Dragons has gone through some vicissitudes over the last few years, but I think the 5th edition of the Player's Handbook puts any edition controversy to bed.
The 3rd edition, its Open Game License, and its 3.5th revision were a golden age for the hobby, but the more tactical combat-oriented 4th edition turned a lot of folks off; and it all went down while Pathfinder, the unofficial 3.75th edition, was coming on strong.
We all remember the dark days of the Edition Wars; they never left some dark corners of the Internet, but 5e seems to be largely immune. I playtested it in early versions and have been playing it with folks from around the Tor offices since then... and now it's bound and printed and finalized! It's different enough from rivals to be its own thing, and it's learned smart lessons from previous editions, combining AD&D 2e's relative simplicity with 3e's customization. There's more of 4e in there then some people will want to admit, too: at-wills, short rests, hit dice, all the bonus actions, races and powers.
