So if you walk into a SQUARE room in the "real" world, that room is not 3D?
Just because the walls in the room aren't round or sloping, or 
whatever, doesn't make the game ENGINE any less 3D.

Heretic, ROTT are not 3D because you don't have 3 coordinates describing
your character, because two objects can't occupy the same X,Y space even
though their Z coordinate may be different.

You confuse the issue.

Since I can walk under the bridge, and have an enemy exist in the same
X,Y space but different Z coordinate (he is right above me), that seems
to be 3D to me.  The DOOM, Heretic, ROTT engines can't have that happen.

To allow the Dark Forces engine to run on as many systems as possible,
Lucas Arts had to make some sacrifices, one of them being having
only vertical walls.  Descent also makes some sacrifices as well (these
have been discussed) to run on as many machines as possible.
