In fact, Supercross Circuit on the Playstation looks better than this N64 title. The tracks have little trackside detail. In the stadium supercross tracks, crowds appear as bland textures with colored squares representing people. Supercross Circuit on the PSX had animated fans waving their arms. And the stadiums in McGrath are nondescript.
Every indoor course has the same character.
I could not recognize the Astrodome circuit with the detail presented. The outdoor motocross courses are not much better. Flat bleachers are sparsely distributed along the course, and for the most part, the only trackside detail are the signs. There is no slowdown or pop-up. But on the other hand, the camera views are somewhat suspect.
