The game definitely plays a lot like ww1 would have played:
Anti air is OP, planes weak, tanks OP, being general infantry sucks unless you're perched up on a hill as a scout (sniper).
The map is very large... and only 1 map choice in the beta...
My poor old graphics card (660) which i've been putting off an upgrade forever is suffering, which isn't a surprise.
The gameplay itself feels more like bf3 than bf4, which is a good thing. It's lighter if you know what i mean.
The most fun i had was on horses, which feel completely out of place and ridiculous, which is exactly the appeal.
Oh and the good ol tell your mate on teamspeak to hold down E, and then swoop and pick them up in the plane.
overall though, i was bored after a few rounds.
