I actually dont mind MW3 at all really from playing it apart from the odd camping dick, however over Xmas i spotted Argos selling BattleField 3 for XBox for £24.99, so thought i'd give it a go.... I've not touched CoD since... BF3 is on a whole different planet of good compared to CoD!
Things like when using a sniper having to aim above the target as bullets drop with distance is a mechanic i particularly like, unlike with CoD where doesnt matter how far away someone is, pointing at them or generally at them still hits them.
Or the fact the maps are sooo much better!
I have to say that i wasnt convinced when i heard lots of other people talking about this game, but having given it a try i can safely say i'm converted!
IMO, if you havent tried it, give it a whirl!!
I heard this before, went and bought it and wasn't impressed, just couldn't get on with it, I've still got it so must give it another go as everyone raves about it
