Picked up Brutal Legend the other day. I'm laughing and laughing, and the soundtrack is fantastic. But I don't think I'm actually enjoying the game. In retrospect, the same rings true for Psychonauts, where the experience was a bigger deal than the gameplay. You know what? I'm okay with that. If Double Fine is to be the company that delivers story and character first, gameplay second, they wouldn't be the first; Hideo Kojima has been doing this shit for a decade, and for my money, Double Fine's stories and characters make me happier. 
 
I gotta say though. I'd totally play a metal-related RTS if it was done properly. On the PC.
