I've never actually been a big fan of the Battlefield series. I did enjoy the Battlefield 3 Multiplayer though (thanks to that Origin Humble Bundle). Overall, I thought that BF3 compared to CoD was more fun in terms of their multiplayer. While CoD put a greater importance on competition and being the absolute best in the entire game, BF3 was more lenient and gave you points for many things be it reviving a team mate, suppression assists etc.
