Can you make a top-down, grid-based game with perspective projection?

Hi again,

I am creating another topic since the nature of my previous question changed.

I am trying to create a top-down RTS-like game. Still figuring it out.

Option A:

Use orthographic projection.

Pros: All sprites are pixel accurate. I can create buildings matching perfectly to the grid.

Cons: No proper zoom in or out. Plus UI scaling problems.

Use perspective projection.

Pros: Can zoom in and out by scaling individual layers. Also synergistic with UI, since I can dump all UI on a different layer.

Cons: Perspective itself. See images below.

Btw, am I missing something, or is the z elevation parameter gone forever?

Thank you.

Well, I feel a bit dumb. :)

I tried using Z elevation for layering sprites on top of each other. And the projection distortion was inevitable. I was not even aware of the Z-order bar, which solved the problem.

My bad, folks. And thanks to Dop2000 again!
