I was always a Battlefield guy, I didn't really make a move. Just never liked the gameplay of CoD. CoD, even titles like MW2, when I played were slow, and almost too predictable.
Battlefield to me is still pretty slow, at least on foot, but offers a lot of unpredictability and variance to a game. Obviously vehicles change that, and that is part of what I like about BF.
Titanfall, isn't Battlefield by any stretch. What it is though, as a BF player, is fun. Much more fun than I've ever had in my attempts to play CoD. Movement is quicker, maps feel better designed, and the atmosphere of it all makes it feel bigger than it really is. Camping doesn't work well, as any perch you choose, can be attacked from multiple angles easily and quickly. Stationary styles of play are pretty much punished, where movement is rewarded. It's a nice break from Battlefield which is the only title I even own on my Xbox One atm.
si c'est ça, c'est exactement ce que j'en attend...
