It was just on sale for $40 not too long ago. Thats when me and a few of my buddies picked it up. Hopefully it will go back on sale for you soon. I think it was for sure a good buy at 40 bucks. Personally I think its even worth the full 60 just because all the game modes they have. Its loads of fun... although if you are getting it for the zombies I'd hold off. While it is a lot of fun there is still only the one map unless you include dead ops arcade. The Easter egg on that map is a must do because its a load of fun but after playing the same map over and over it can get a bit old.
