It’s a 1992 Sonic branded Milton Bradley board game, and you don’t see these often. It is used, and it does have a couple pieces missing. But you can play through four zones from the original game with a cutout Sonic: Green Hill, Labyrinth, Marble, and Scrap Brain.
It’s cheap, and you don’t have to worry about physics. Collectors, take note.
Sold for $14.
