DC: "Fallout: New Vegas introduces you to some refined things. There is no better place to start then with the VATS. The Vault-Tec Assisted Targeting System (VATS) has been refined in a more balanced manner. I know for some people playing Fallout 3 and then playing Fallout: New Vegas is quite jarring when you're using VATS. Depending on the weapons you use determines how much damage you are going to do to your enemy."
