BF3
Battlefield 3 (commonly abbreviated to BF3) is a first-person shooter video game developed by EA Digital Illusions CE and published by Electronic Arts. It features huge landscapes, numerous drivable vehicles, and a large number of weapons and unlockables, and not to mention JETS!

Despite having a boring and short single player, the multiplayer aspect of BF3 is better than any competitor and is no doubt the best multiplayer first-person shooter yet!

Many comparisons have been made between Call of Duty Modern Warfare 3 (MW3) and Battlefield 3 and results show that Battlefield 3 is indeed the better of the two.

Girl 2 - "Aww that sucks! Tell him to get BF3. I play it with my boyfriend every day and we both love it!"

BF3 - Boobie For 3! Cleveland Cavaliers PG Daniel "Boobie" Gibson draining a shot from 3-point range.
Commentator: The Pistons are putting the pressure on LeBron with the double team, he finds Boobie open at the top of the key; he fires! And BF3!
