My impression is that the game feels it was more designed for console and not a PC First Person Shooter experience. I have played every Far Cry on PC and this is by far the most arcade feeling of all of them. The plane even self corrects. It does not have the immersive FPS feeling as FC1 to FC4. I feel I am one step shy of having the floating Playstation symbols telling me what button to press on screen when an enemy approaches.
p.s I am not including Primal here as it was a joke.
