The thing people find interesting about this (and the Fantasy Zone game mentioned on the emuchat forum) is it has Sonic (or for Fantasy Zone an otherwise memorable game). The graphics and sound are awesome and on old arcade hardware never to be made again and it's rare forms of favorite characters and games. If it was random stupid characters instead of Sonic there would be 1% the interest. It's sort of similar to Ganbare Marin-kun, the hardware was CPS1 so it's of interest because its hardware is so widely loved that we want everything that ran on it.
