I tried sc2 and WoW, and they both look really awesome. I haven't tried a game that uses iron sights yet, just crosshairs.....With l4d2 the crosshairs for the survivors are good, but when it comes to the crosshairs with the infected, they look a little strange because they have the original circle crosshair then the "recharge" circle, so it looks a bit confusing at first, but you adjust to it after a while.
