Yeah I was hoping for something more like the Cruis’n USA racing games where the world is scrolling at you and your character stays stationary.
What do you mean by realistic? I guess you could throw shading/lighting in, but then you're playing a 1D version of a remastered Mario Bros rather than the original.
I just mean some element of 3d. Anything. It could just be a blue sky in front of you and the faces of goombas and blocks are coming towards you as you walk/run forward (maybe you call that 2d with forward/backward movement). You would have up/down lookaround as well (no side to side obviously). The real question is: could you build this "world" with only data from an .nes rom?
There are several VR 3D Super Mario Bros adaptations which are easily found on google. But of course they have to take liberties in the Z plane.
