Think maybe you should read this...........

I wondered whether someone would make that point :)

It's true that even "isometric" games was strictly dimetric (and they should probably have been called that). Pixel dimensions simply precluded actual isometric angles -- but the standard approximation is reasonably close.

So I acknowledge your point, but I don't mind letting that one slide.

A 3D game with blatant perspective referring to itself as isometric, however, is quite a different level of incorrect!
