I have the PC version, mainly grabbed it to see how my new computer I just built would handle the graphics (intel i7 quad-core 920, 12g ram, bfg 1792 gddr3 gtx 295, & Win7 64bit) since the only 'stress' test I've tried is CAD models with Alibre .
Installation was pita. It didn't autoinstall from the dvd's, it kept trying to force a download (at 12+ hours est). Finally got it to install off the dvd's after messing with it for @40 minutes.
Single Player campain has been good so far but the multiplayer sucks. No party chat, and granted I'm way out of FPS practice, but with thier matchmaking... it makes it pretty hard to get into a match of people just slightly better than you to force you to learn to get better.
