Crysis 2's soundtrack was nothing to write home about. "Wow, Hans Zimmer!!" ...but he only wrote one miserable track, and it's not even that good considering his talent. I think they just wanted to tack his name onto the box as a marketing gimmick. It reminds me how so much was made of Patrick Stewart and Sean Bean voicing characters in Oblivion, like it somehow made up for the fact that the other 90% of the voice acting was downright atrocious.
I sure hope the new Mirror's Edge game has the same composer. The music isn't really my style, but it fit so beautifully with the game that I can't imagine them being able to re-capture the same atmosphere otherwise.
