Summary: Superman on the N46 is one of those games like ET on the Atari 2600 and Action 52 on the NES that has become notorious for its unparallelled awfulness. Graphically it isn't too bad for its time, with half-decent 3D character and building models as Superman flies about a city. Objects only become visible from a short distance away however, and worse than that most of the city is utterly flat, with only a few buildings actually cropping up here and there.
Pros: graphics are ok for the time
Cons: infuriating and dull beyond words. No fun whatsoever.
