The guy who composed the music said EA rushed the game out. That it was to cash in on the first game's success, and they wanted the sequel released now.

I'll freely admit I've never played DA2. But it's apparent to me from reading the user comments about the game, that it is subpar. Really pathetic for a so called Bioware title. Oh how the mighty have fallen. But truthfully it's the same studio in name only to the powerhouse it used to be. I get a kick out of the passionate defenders.
DA2 is weird. I enjoy the hell out of it and I think it does some things better than recent Bioware games, but I notice a lot of problems it has too. My main focus now is just having fun with the game though. When I beat it or get sick of it I'll figure out where my feelings settle. It may end up being Bioware's worst game so far, but considering the company's pedigree that still puts it in a good position.
