If we close our eyes for the CoD clone stuff, ACM have more content in it than AvP '10 - more features including coop campaign, customization, class making, objective based modes, its basically in the same timeline like the movie so we have exact copies of the weapons, armors etc. unlike in AvP, we will have the chance to revisit Hadley's Hope (even if its ridiculous canon wise) etc. etc.. I mean ACM is already better than AvP '10 because of its content, without GBX trying to make it "for the fans" it still will be the best Colonial Marines - Aliens like experience up to date. I am sure everybody who don't like preds at all and he enjoyed all marines vs aliens only modes in the previous AvP game, will love ACM.
