That's fair enough. It might not be worth the effort. Pokemon is probably one of the games that gets away with not doing much of the film trickery, but I seem to remember it doing some. Then again it can also get around it by doing things like the movement of the animated character in from offscreen when fights begin. That was older Pokemon though, and I don't remember enough of Sword and Shield to say if it still does do that...

A better example, and probably a more fitting one, is old FF7. It's aged fairly poorly, so I wouldn't suggest you play it again, but if you look at some of the cutscenes there's a minimal amount of camera movement. It's a bit different in that it has a fixed camera for some areas, and that gives more of an intimate feel to some of the scenes, but it's largely centered on the character from overhead, like the one you currently have in the overworld. There's not a great deal of intentional camera movement in scenes but when it's there it adds a lot, panning slightly to a set piece or to a character entering the scene. I assume it was also a pain to implement though.
