Why is battlefield 3 good

There are many reasons to say that it is good and to say that it is bad. For example, I may think that since it has big maps with air, land, and water vehicles it is a great game. You may like much smaller maps with no vehicles. Battlefield 3 does have a bunch of close quarters maps for those people who like smaller maps now with the release of Close Quarters though. Battlefield 3 tries to be as realistic as possible, whereas you may like unrealistic games. It is all a matter of opinion.
