I'm surprised no one is talking about it here, but hot damn, Diablo III sure looks pretty nifty.
I never got into Diablo II much at all, and probably won't get this game (Hack 'n slash RPG's are really not my type of game), but that doesn't mean I can't appreciate the artwork and detail that Blizzard put into this game. Just watching this 20 minute gameplay footage, you get to see some of really small details which are really cool (like things falling off the ledge when you hit the wall hard etc). The art style and 3D is amazing. I thought Blizzard had a mass exodus of key people a few years ago? It certainly hasn't hurt them.
