"Battlefield: Bad Company 2 is a better game than Call of Duty: Modern Warfare 2." Those are the first 15 words you will see when reading the In This Electronic War, Momentum Shifts to the Underdog New York Times review. The review also mentions how great the PC experience is, especially with a three-monitor setup.
This is an awesome point!!!
Its just another opinion that means nothing, both games have pros and cons. Some people like one some people like both, so whats the big deal, as long as you enjoy yourself on either. You're like little children arguing in a play ground!
