I don't blame Bohemia for throwing all their eggs into this basket since it sold tons of copies of Arma 2. The engine updates seem nice. I'm hoping they come up with a way to encourage teamwork and not just have PvP with zombies in the background.
Might help if there wasn't an M4 with 200 rounds in every shed and food everywhere. The whole "survival" aspect (outside of other people) went to the wayside pretty quickly in terms of finding resources to survive when there is "loot" in abundance all the time.
