BF3 is not even close be alike eachother. I admit, that BF3 is more like real war, and that MW3 is more balance towards vehicles. Like, you can't drive a vehicle in MW3, only have control of missils or helicopters. In BF3 you'll get the option, between many vehicles, such as tanks, airplanes, helicopters etc. MW3 is more for people, who likes to have fun gettin' good killcams and good snipin' skills. BF3 is more serious, imo. So, I will go for MW3, since I'm buyin' it myself (Xbox, since Ps3 sucks).
