Damn man. I'm really sorry that I never jumped on this. Not only is the game super fun thus far, it's goofy (I really don't find this all that off-putting... yeah the humor isn't high, but this is hardly Duke Nukem level stuff, and it's very well-acted and natural), it's really quite pretty with some great sets and awesome monsters, and the soundtrack is fucking amazing.
I always wanted to try it but just never got around to grabbing a copy. It's finally cheap enough, and man, so fun. I'm looking forward to the next two acts.
