Could "Call of Duty" be good?

[Your Computer]

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.
