ummmm, well I just went out and got my copy and.... well, I think it is not that bad tbh.
It feels solid enough and is more immediate than ArmA2. The cross com system of ordering, while not massively intuitive, I think is better than ArmA's system. Changing weapons and ammo type, also not a problem. vaulting walls, the hand was there right away.
Graphics - not amazing, but on par with ArmA2 imo and certainly not detrimental to game.
Enemy AI - yea, might be a bit ropey, but I will reserve judgement on it until I play a few missions in. They certainly returned fire, and took out one of my guys.
Squad AI - also yea - would like a bit more control, but then again it might be me not being a good commander yet, don't know. However they moved when told and did not cross my FOV. though I did tend to put my self forward. again - time will tell.
Ballistics - I don't know, I don't read Janes. But I could not take out infantry at 400m with an assault rifle very easily, so I don't know if it is accurately modelled but there must be something there.
I can't understand some of you guys who played it for 20 mins and then uninstalled, I think the game deserves more than that.
I am pleased with it so far, but as I said in an earlier post, I am quite forgiving of games. trying coop with a mate tonight and will report on performance.
