Related... for a native GB/DMG/Z80 take ... the original first person shooter for the Game Boy was Faceball 2000. (1991) The studio was full of coders who loved and admired Wolf 3D and everything that followed. By day, we were stuck coding variations of Z80 and 6502 assembly. I did the Sega Game Gear port. It was not good.
CPU completely halts, so you can't use the joypad or sound anymore.

Cruisin Exotica had better graphics/art maybe but that's it, Supercross did more credible jumps and perspective tricks under an 8 bit console.
On 16 bit racers, probably the patched Genesis ROMs for Road Rash I-III would be one of the best faux 3D games ever before 32 bit consoles and computers rendered (no pun intended) them obsolete. They add a far better framerate while being totally compatible for consoles. You can get thrown from your bike and "explore" the environment on your own with nice scaling tricks.
Lotus 3 for the Amiga achieved believable perspective based techniques too to simulate a 3D cliff in a pure 2D game, at leat racing aside. These were great too.
Now, once Road Rash 3D hit the PSX (and Ridge Racer among Daytona Usa, altough Daytona's render distance sucked and RR hided it far better) the 2D games' days were numbered. With Road Rash 3D you could totally free roam around on your own outside the circuit, go anywhere, do 360 degree turns and be sure that any town/road you would be seeing further in the horizon would be a rideable path. It was, and that was mind blowing, compared to the static screens from 2D games.
Imagine a pre-Street View world where video games would be almost the sole way (among movies and series OFC) to experience yourself the rest of the world, or America if you were an European. No, multimedia CD's were expensive and your parent's wouldn't buy you a "Virtual Tour CD" from Paris or the like, it had no actual use except if it were something like Italy or France showed from a touristical/historical basis. These first videogames gave me a roaming experience until GTA III was a thing. Later, yes, Street View killed it because, you know, you got the real thing in your computer, but the magic was lost a little.
