As a first person player the weather should affect my and the crews vision . The screen should be my eyes so if its raining then there should be water getting in your eyes . I should be able to put a rain hat on and improve my vision. If its large seas then tie the bow wave to the action of sea water getting in my eyes . I should have the ability to put on a pair of goggles . I should be able to wipe water from the goggles by pressing a key and the same to wipe my eyes . The screen should be my eyes . If there should be water in my eyes then make the screen blurry etc etc etc
