So far I'm loving it. I love the control, the movement, and the overall atmosphere of the game. I'm mainly playing team deathmatch using scout sniping. It's hard but rewarding.
Been playing it myself every now and then with my brother and a few of his friends. It's definitely one of the better Battlefield games we've had in a long while. I usually like playing the classic Conquest or the new Operations. I really like Operations for feeling kind of like an actual battlefield (heh). One side pushes and the other holds the line. Think I almost like it more than Conquest.
I at first only had interest in playing as Scout because what is the fun in running around with SMGs and not bolt-action rifles in a WWI setting, but I've come to enjoy all the classes and utilize them all well. Still don't use the SMGs though. Prefer trench guns.
But yeah, it's a solid Battlefield game.
I had it but sold it but I still liked it and I might get it again as a digital download. As for my opinion of the game----it's okay although most of WW1 was fought with bolt action rifles with VERY little fully automatic weapons I like to think of BF1 as more of an alternative WW1 then an actual historic WW1. My favorite modes are:
Operations.
War Pigeons.
Rush (this is SO Walker Assault but without the walkers).
