MW2 strikes me as one of those dull,annual outing franchises,there's nothing special about a game like that,to me anyway.
The people I know personally who applaud MW2 are the people who games only on the odd occasion.A true gamer will always go for Killzone,Battlefield,R:FOM (not Resistance2 as it's shit) and MAG etc
Those games truly put you in situations that are dangerously similar to the real life battlefields.Now remember I say situations not environments,cause that's what MW2 puts you in,environments.
