My wife bought the game today and all I can say is I cannot believe it actually made it through QA.
Serious bug where it freezes my computer and mouse clicks just result in a beep. Finally after a bit the whole monitor just shuts off and goes into standby. Come back up and check temps and everything is just fine. Granted it's about 1 or 2 min to come back up but the temps are fine.
After a few of these I go to the forums and you would not believe how many people either cannot install, play, or can only play for an hour or so before it crashes.
