It looks pretty bad to me, worse than MW3 in a way. It just reminds me of an ambitious mod (that actually got completed due to being a proper game). Maybe it is because I expect the same old crap from Activision- reskinned game, few new mechanics, same old stuff.
I liked Black Ops, so I suppose well done to them for trying something different. However, I'd rather they'd set the game during the late 70s and 80s. You have the oil crisis, the Iranian Revolution, the Iranian Hostage Crisis/failed rescue, loads of third world revolutions and break downs, the Soviet invasion of Afghanistan (could link up to Cod4 by working with a future terrorist as a US spec op- that'd be the controversy sorted), the Falklands War, Iranian Contraband scandal, the Iranian Embassy Siege in London, the final money escalation of the Cold War under Reagan (Star Wars program for example), Chernobyl, the USSR beginning to break down and fall apart, and anything else I've forgotten. Plus all the completely 'made up' scenarios they could use.
Would have been far better.
Edit: shit, they could have even had a Rambo rip off segment at the start of the game in Media Res where you kill loads of national guard in a blood filled rage, shoot up a small town, only to be stopped by your 'Nam commander.
