Only two American home systems received a port of 720, the Commodore 64 and the Nintendo Entertainment System. Both ports were published by Mindscape, and have a lot in common even beyond that. Each features the same slimmed-down design of Skate City, and both sport the same skimpy soundtrack, offering only four of the arcade's dozen or so tracks. The similar title screens, different from the arcade's, and the identical graphics of the player and other inhabitants of Skate City, further show that a lot of effort was shared between the two systems.
Fortunately, unlike other pairs of systems that often suffered because of shared code, the NES and the C-64 are both up to the task of a game like 720, and neither port disappoints. Sure there are obvious compromises, including those mentioned earlier, but most of the game survives the transition to each system intact. The park events are here, and so are the shops, the other quirky inhabitants of Skate City, and yes, even the bees. Gone of course is the narrator threatening you to "Skate or Die!" but each version still makes it obvious when it's time to get skating or get stung.
It's difficult to say which port is better. The C-64 game has better sound, but the NES doesn't have to wait for a disk drive. The arcade's original 360-degree joystick is harder to simulate with a Nintendo joypad than with a Commodore joystick, but the graphics on the NES flow a little more smoothly compared to the awkward jagged scrolling of Skate City on the C-64. In the end it's pretty much a wash. But if you're a fan of '80s game music, definitely get the Commodore port.
