Would it be a good solution to have more camera freedom at eye level, and less visibility when zoomed out?
There are advantages to the game park design, but it would be good to keep that design hidden from view, to achieve a somewhat credible world. That would mean no more outlines on the mini map, or no mini map at all, and less ability to get bird's-eye views of the environment. The latter could be achieved by limiting viewpoint height and viewpoint position, and/or by hiding faraway surroundings.
Limiting perspectives that could never be obtained by the playable characters would need to be compensated by more freedom at eye level. For instance, being able to look up.
