OT Battlefield 3 vs MW3
 

Had a chance to play both and Battlefield 3 kicks MW3 ass.

Absolutely. I didn't mind MW3's single player campaign (better than Battlefield 3's) but for multiplayer BF3 is vastly superior. The clincher for me is that MW3 (in fact all the Modern Warfare games so far) very quickly get completely overrun by cheaters. It's incredibly easy to buy or otherwise obtain cheater software for MW3 and it is regularly updated to get around anti-cheat software.

WOW just did the F-18 part of the campaign and it was the best flight combat I have ever been in.
