I'm not usually a fan of watching other people play D&D. I mean, I like playing it myself, and the Acquisitions Incorporated games put on by Wizards of the Coast and Penny Arcade and endlessly entertaining, but it really takes the right people with the right amount of enthusiasm to keep the game from being both boring to play and boring to watch. I guess that's what I'm worried about. A lot of the Giant Bomb staff haven't ever seemed too keen on the idea, and that can really quickly turn into just not being into it, which then makes the game boring.
All that said, I had a great time watching everyone go from slightly interested to being goddamned miserable when they played Fortune Street, so hey, maybe this'll be like that.
