Most of the reviews for the Genesis game were generally above average to good or great. Maybe like a 7-8.5 type of game or a B/B+? The game was designed for the Sega Genesis / Mega Drive first. It's a neat final Sonic game released for the system. I had a copy. Most of the complaints came from the Saturn port which was released a little later. With disappointment that it wasn't the 'next gen' Sonic reviewers were hoping for. But for a Genesis - Saturn port, the reviews were also above average. The Saturn version does add the 3D bonus stages, some higher quality sprites and use of polygons in some areas. Richard Jacques soundtrack some high colour FMV. Travellers tales was on a role with licensed games at this point, They had The Timeless Adventures of Mickey Mouse for the 16bit systems, Toy Story for the Genesis/ SNES, Sonic Team contracted them for outsourcing. They made this and Sonic R.
