Which November release should I purchase?

Massive dilemma - Gran Turismo 5, Assassins Creed: Brotherhood, and Call of Duty: Black Ops for PS3 all come out in the same month, and I can only afford one of them! Which one should I go for first?

Thanks for your help.

If I could only choose one... AC-Brotherhood.

I would get AC:Brotherhood.

Thanks all! I was leaning towards Brotherhood as well. Looks like that is the one I will be going for.
