Let me just start by saying I've played all of the Splinter Cells, and I'm a huge fan of the series. I just finished the game on realistic a little while ago, and there are MANY situations where it is FAR easier to sneak past enemies than shoot them. It's good because in this Splinter Cell, you have a choice between stealth and action. For instance, in Chaos Theory you were penalized for almost every mistake, even when a guard sees you a split second before you drive a knife into his spine, and then every gaurd would magically know where you were and come sprinting over and kill you in a split second because the accuracy of your guns made them almost useless in combat. That didn't make sense, but whatever. The previous Splinter Cells were for perfectionists, but they were very frustrating at times. And honestly, who didn't run through all the levels killing everyone after they'd finished it anyway?
