Comment Re:How stupid you can be to call DOOM 2D (Score 1) 117

It had limitations, but still every object had 3 coordinates.

"Illusion of 3D" my ass. Every 3d game is "an illusion of 3d".

Not quite. The reason it's not a true 3d engine is because of how the map is represented. The map is composed of 2 dimensional planes each with a specific height. This might sound like 3d, but it's not. For example, no two planes can overlap in the x, y dimension--no bridges or tunnels with floors above them. So it's like flat 2d map but subdivided in to pieces (sectors in doom speak) that each have a height projected up from them.
