I got it today and played for seven hours with only one bathroom break, i had a headache after a few hours, but everything is fine
Next i shall check out multiplayer and see if the Vista and Windows computer can run it (I'm having more doubts with the Vista computer because that has problems with Left 4 Dead 2 being slow at times)
I apologize to anyone who wanted to play with me or just talk to me while i was playing today, but i hate how typing works on a PS3 and i did not have a USB keyboard to plug in
