Making the freelook camera able to turn only when clicked would be Nice. Also being able to somewhat Control the CCTV could be fun. Not sure what purpose it would serve, but it could eb neat to have some Limited movement on the CCTV, allowing you to look around a little bit, though perhaps not look so far that the player disappears from view.
Camera controllers are really fun to make and contribute a lot to a game’s look and feel. I think experimenting with new ones is an awesome idea.
