I have COD MW and really enjoyed that game. So i decided to buy Black ops when it came out. I for one think it's great and any issues I have are very minor. But some people just hate it.
I truthfullycan not see why. The only reason I can come up with is that these people are narrow minded and can not see past what they think they game should be. So when it does not meet their expectations.....it sucks. But in the end you need to recognize that it is a great game.
P.S. And if it sucks that bad then why has there been more then 100,000 online at any given time. Peaking from what I have seen personally to over a million.
