SoF2 sucks, even more than VC!
VC is not a bad game at all, I have never seen such a realistic nature and atmosphere in any game before. The sounds are extremely good aswell. Weapons are well-made. The MP is a bit bad coded, but I guess it will be changed later (on low ping servers I've got no problems playing MP).
VC also adds a new tactical element in MP, as you got to hide behind trees anbd other obstacles, then you got to lean, crouch etc, quite a lot.
The game is not based on shoot and run tactics aka Unreal or CS.
