Both have there pros and cons. I found the campaign easier on BC2 on the hardest difficulty, compared to MW2. More storyline in MW2 as well. Fighting is more compact, and higher paced in MW2. Maps are a helluva lot smaller. BC2 almost everything can be destroyed. A pain in the ass when you are on the receiving end of a tank. MW2, takes a whole clip to bring someone down BC2, a few well aimed bursts, and the opponent is dead Harder to level in BC2, I've just now cracked lvl 12 at 16 hours. Haven't found ridiculous glitches in BC2 yet. Although I have been kills by a guy in a rock, and a tree. BC2 is def something to play with friends online. Because it sucks having to run from one point to another, since the maps are so damn big. With a friend squad you can spawn on one another. BC2, there isn't alot of camping, at least not the whorish camping in MW2. BC2, knife action is a little slow for my liking, but seems more realistic.
