How fun is this game? I consider myself a WarZ survivor I survived one of the worse games I ever played. Is it a night and day difference? I bought and got refund on WarZ on steam and used that refund money to get Arma 2. Also how well can I run this game. I got a GTX 560 TI,AMD Athlon II X4 OC 3.2 Ghz 8GB Ram.
