No it not. If you spent 60 dollars in the first place of that game, I would feel bad enough because what you're willing to spend on the new one, however I don't see any point of you spending all that money for a game that doubles what it cost now.
Well, did you enjoy the previous games? If you spent 100's of hours playing mw2 or black ops, then yes, it might be worthwhile for you. If you don't play games online, then no. It would not be worth the $60.
