Call of Duty maps are small, and it is focused on the run and gun play style, not much else. Small teams, the overall goal is to keep the action nonstop, with added kill streak abilities to give you incentive. Battlefield maps are larger because they incorparate a large variety of vehicles both air, ground, and sea, and the anti vehicle measures. Battlefield encourages teamwork i.e., squad spawns, commander slot, mini map and 3D hud spotting mechanic. Battlefield is not a simulator more like an larger arcade shooter. Call of Duty players, those who truly enjoy the game do not enjoy battlefield as much because of the larger amount of variables, and a change in gaming mechanics, which is coincides with the a common apprehension we humans have concerning change or something new.
