Have you played the Catacomb Abyss/Armageddon/Apocalypse trilogy as well?

It has some pretty neat features - e.g. the status bar shows you the name of the room you are currently in ("small closet", "dark chapel", "slimy sewer", etc.), there is a radar-like feature that shows nearby enemies as dots in different colors (e.g. purple for undead, blue for demons, etc.) Most impressively, the ceiling color is dynamic - like it can become darker to simulate nightfall... or it can even flash white, imitating a thunderstorm in the outdoor levels!

And in the third game there is even a basic form of hub gameplay (the hub level has exits to 4 others levels, you have to collect 4 keys from these levels in order to access the fifth exit and leave the hub).

The 3D rendering, however, is worse than Wolfenstein's - walls (especially small alcoves) become distorted when you view them from a certain angle.
