I got ARMA II...its a different game unlike call of duty takes some getting used to me and my buddies do custom missions on hard...
favorite part is creating missions for me ,especially convoys
with 1 team has to get theirs across point A to B while other has to prevent..we do lack people but the AI somewhat fills it in. Like I said its hard to get decent/create custom missions but I like it to get away from IRL,etc.
DaYz ...well its a whole another story I personally played it when it first released and zombies didn't spawn often or only in cluster groups which felt unreal and enemy people are your primary concern, not zombies
