Non game spoiler and all, but if you own a PS3, prepare for some completely unsatisfying experiences around actually playing the game. It's been sitting in my drive for an hour now, and much like other games I've seen on the console (Uncharted 2, I'm looking at you), it wants to install. And install, and configure, and install, and install.
Of that one hour, I got about 2 minutes of gameplay. Buy it for PC or 360 if you have the chance.
If the above post didn't offend you, you're probably reading it wrong.
