lmao, you complain about the graphics then decide to stick to battlefield?
Stalker came out 2007, ArmA, 2006. Graphics aren't 5x worse. You just enjoy run and shoot'em up'erz rather then take your time slowly and work as a term [as you would in real life] To you, thats not fun but to many that want a more military experiance, it's awesome. Not only that, ArmA has 1000x more potential then any of the BF series that has come out. Also, more people hack in BF2/2142 cause they wanna unlock/gain ranks, etc. Type in Youtube 2142 hack and you'll see tons of crap, type in ArmA and theres like what, 1 or 2? Of course your not gonna like ArmA if your use to playing the BF series of fast paced action, your just gonna run in fast and die even faster [Which i bet you did, Especially in Co-op]
P.S: Not to sound like i'm just a ArmA fanboy cause i've been playing alot of BF2 lately and now especially with the new Desert Conflict mod that came out. I won't even touch stalker in terms on Multiplayer lool.. [32 ppl online lool SoF2 has more then that and it had big grapihcs at that time]
