I enjoyed it a lot, but then again I'm a devoted fan of the series. But having said that, there were some things I didn't care for. The game was too linear and didn't "open up" until the game was almost over. No real side missions and a few other things were disappointing but other than that, I couldn't really fault the game.
It was working fine last night when playing Borderlands. I just had 2 trophies that didn't unlock like they were supposed to and that's when I read about this system issue. I've since turned it off (last night) and haven't turned it back on today in case it causes problems.
