In my mind, I believe, along with the big things, that little things make a game much better. So I think these smaller changes could just help make every FPSC game look like it was polished way more than usual. For example:
-head bob while walking and reloading (reanimating)
-Better sound (dynamic to position of enemy shooting at you...)
-prone for player and NPCs
-trees swaying in the breeze (animating)
-the 'puff' decal (the debris off a wall or material when shot, the dust puff) should be vertical for ground and horizontal when coming off a wall
