This is not a Call of Duty versus Battle field discussion. But rather a friend asked me the other that he was planning on buying BF4 as he'd never played a battlefield game before. He had however played Call of Duty obsessively since Modern Warfare 2 and wanted to know if he could just... "transfer" his FPS skill over- I told him this: Yes and no I think is the answer. It all depends on how you play your first person shooter games... and also, who you're playing them with. Yes it might be a steep learning curve if you are used to be being the one man Rambo fighting machine that works for a lot of people in COD (such as myself). How Battlefield comes into it's own is in the tactical side of things. The best way to play it is with a group of people who can choreograph tactic together. For example I play with a bunch of work friends and every day at work we also talk about the games we played last night, and things that come up are: What went wrong with how we handled last night's game? what went good? How could we change our approach to a certain situation or a certain map to get an advantage over other players? We come up with very good answers for this and then, when we come to play Battlefield that night, we implement them and continue refining our tactics to make us unstoppable. Then every now and then I want to play solo, so I decide to play a game of COD- because solo simply doesn't work on Battlefield. What do you guys think? how steep is the learning curve really from COD to BF?
