This is as close as we will ever get...
Sega once decided to produce an
Spin-Off Sonic game based on the popular
Sonic Sat Am universe. The game was put in the hands of the producer
Comix Zone.
The game was to have 36-bits graphics (
something new at the time), and it looked... decent.
Other games that include
Sonic Sat Am characters include
Sonic Blast and
Sonic the Hedgehog Spinball.
