In Grand Theft Auto 4 and 5, Rockstar added a cinematic camera feature that allowed you to have a rotating cinematic view of what you were driving. As a car enthusiast, one of my favorite activities was adding modded, real-world vehicles into the game and driving them around the city using the cinematic camera.
Since Forza creates such beautiful worlds and realistic vehicle models, to enhance the experience, a cinematic would be a fantastic addition.
I think there is a lot of room for camera improvements in general, even beyond this. I love playing GT7, winning a race, then watching the replay camera to see all my overtakes throughout the race. The replay camera in FH5 focuses ONLY on your car. Which is cool and all but… what about the race? I like cameras that are sitting static throughout the course and it switches between them, tracking your car. You get a “spectator” view of the race. I can never see what’s going on in FH5’s replay camera, just my car.
