CNN Article On D&D
The article talks about how a lot of players have left the hobby due to lifestyle changes, which is true. People get jobs, families and other obligations and can't make the time to play.
A couple of things I find interesting. One is no mention for another reason for loss of players from the current game, the "edition wars" between the Old School/ 3.5 camps and 4e. These are people that still play, but don't buy WotC's product in doing so.
The other thing is that one of the complaints about 4e is that fights take too long. WotC deals with this by prepackaging everything for the adventure as opposed to looking at the mechanics.
Check out the article, if nothing else it's nice to see D&D get some press that doesn't involve us being evil. Along with comic books and rock & roll.
