Found this short, interesting, well-done documentary about playing D&D on wilwheaton.net:
1. 4E requires a lot of physical gear to play!
2. I think there's a bit too much of the "wish-fulfillment through my character" and "nerds are people too" vibes happening in the film. I get that wish-fulfillment is a part of RPGing, but I think the film overstates it as a rationale. Similarly, I think most of us -- jocks and geeks alike :) -- have gotten beyond bagging on anyone else's hobby.
3. I think it gets the communal fun aspect of gaming just right!
