Doom was a 2D space that looked like a 3D space due to rendering tricks. You could never move along the Z-axis though because the engine doesn't represent, calculate, or store one. That's why you can't jump, and there are no overlapping areas of the maps.

Regardless of the “technicalities”. My point was that this, and other 3D games were something that Amiga could not do well - whether 3D, or “simulated 3D”.
