Were you dropped on your head as a child, then repeatedly smacked to ensure brain damage? That's like saying GTA is like COD because it has guns. Battlefield is vastly superior and vastly better due to- 1) A modern physics engine with more destructibility. 2) Massive, sandbox maps. 3) Objectives that force you to be a team as otherwise you'll lose. 4) Naturally evolving games that turn players into a singular, organic force that commonly adapts to face new threats. 5) Vehicles. 6) Larger teams. 7) Actual skill is required to snipe players. 8) Pilotable, constantly spawning aircraft. 9) -blam!-ing Battlefield man.
