Could "Call of Duty" be good?

[The chaser]

Googol, S.T.A.L.K.E.R it's one of the best games I have ever played: Not only for the shooting, because of the environment:

There's a part of Stalker: Shadow of Chernobyl where you go to some sort of underground facility. There are some enemies and mutants, but, do you really know what scared me? The good lighting and the background sounds (Doors opening, for example).

And, Stalker is quite real, in my opinion: You can't go like rambo, you have to carefully hide behind certain objects, or a militar will kill you with 3 bullets of his AK (oh, there aren't tons of ammo too).

Stalker is a very good choice to begin with. I personally think that a horror and action lover should not miss it.
