I've played MW and it just doesn't come close to BF in many ways. There is so much to do in BF with all the different vehicles on land, air and sea. MW multiplayer is about as limited as a simgle player campaign.
The beta was really amazing when they released the second map. That had heli's and jets and jeeps and tanks in it. it was sooooo muuuuch funnnnn!!!
I also can't wait to play the remake of Karkand!! If you don't know, Karkand was the most famous map played in BF2. Ughh, its gonna be amazing. They are bring 4 of the top BF2 maps back to BF3 as a bonus.
