John Carmack Quotes
To the game code, the world is still just a tile map, but for rendering, each map was exported as a general-purpose 3D model, and the artists could then go through it and spend the polygons any way they liked, without the limits of line-of-constant-z software rasterization that we lived with on the mobile phones.
