Could "Call of Duty" be good?

[Bridge]

I want that the game feels earnestly and real. Not like it's just a game.

You're not going to get that from CoD, let alone CoD: Ghosts. Gameplay wise, i don't see much of a difference between Ghosts and previous CoD titles. S.T.A.L.K.E.R. with the STALKER Complete mods would be a better choice.

They are completely amazing but I think everything they add makes the game lose its focus a bit. I think vanilla STALKER is good enough on its own and the game should probably be played that way first before installing all of the mods (no matter how good they are).
