Honestly?? I think BLOPS was really sad! Sory might have been tolerable, but the gameplay, graphics and overall experience was trash! I agree with one of the above posters that Infinity Ward does a better job. The MW series is much better than WaW and BLOPS. I played BLOPS the first time around and when I tried playing it the second time, just didn't happen.
MW 1 and 2 on the other hand has much more replay value and I can run through them again and again. I guess that's why I'm counting on MW3 to do some damage control. Will definitely be buying it.
