Change the camera focal length depending on viewing angle to make it easier to build to the grid
The idea came to me while trying to place retaining walls where I tilt the camera up high to try to see the grid better. The camera perspective still makes it very difficult to align the pieces.
If you were to change the focal length of the camera (or any other camera shenanigans) to more closely approximate a orthographic view when you view the scene from top down would make this less of an issue.
I've attached one image of a Blender mockup where the focal length is set to 180mm to show the effect.
It would take some fiddling with the curves to get it feeling right, not just lerp, but I think it would improve the planning part of the game without taking away the overall look and feeling.
