I think this one may be great, but I am more interested in Mafia II right now. Considering this western theme never appealed to me, that's not hard to understand.
I believe the only western movie I enjoyed was Unforgiven but even so, that movie is so great that I believe it is way being its genre.
Two of my cousins are buying this game, so I'll probably get it from one of them when they finish it.
But still, it does look fenomenal and knowing Rockstar's reputation, I think that at the very least, it'll be really damn good!
