because veichles are like simulation, there easy to drive fly etc, you should try them on bf2 from 2005 on pc you will then see how easy they are to fly in bf3
people are just to used to crap games like cod and cant stand proper games that require tactics and skill to play the game properly
i could quite happily go on cod with 2 weapons and wipe the floor with most people on bf3 im getting my arse kicked all over the place but i enjoy it becuase its a game i can play with my mates and have proper games
