Good First Person Shooters?

It depends what kind of game style you looking for. For example, Arma 3 is tactical, Its realistic-ish style. You can go for arma 3. Or CSGO is more team related and you need to defuse bomb etc, where you dont have the options like in Arma 3 to lean right or left.

My fav 1st person shooter is probably Battlefield 4. I love the game and it deserves credit, aswell with arma 3.
