Interesting that using a perspective camera from very far away (so large distance to scene but low FOV) is basically an orthographic camera. It looks nice having a top down view with just a little bit of perspective, versus fully orthographic. Gives the user a bit more spatial awareness to work with by being able to see side planes when head on. It doesn't work when you're trying to align things to a grid orthographically, nor does it keep the math simple like it is when handling just orthographic cameras.
