Christian Whitehead (also called Taxman and a long-time member of Sonic communities) created the Retro Engine and used Sonic CD to demo it. There's a cool story to how this game made it to mobile. Not many people played this one because it was on Sega CD, the add-on to the Sega Genesis. soundtrack that so many Sonic fans are fond of. There's also the amazing soundtracks, both the original Japanese one​ and Spencer Nilsen's U.S. It's a challenging game, but a great one, and perhaps the pinnacle of the series. Do all that, and you can get the best ending possible.Īs far as Sonic games go, it's surprisingly involved, and its levels have a sense of massive scale that the Genesis games didn't have.

And then, you have to find certain destructible objects in acts 1 and 2 to trigger the good future in act 3, a boss fight. Each act has a past, present, and future that you can reach, but only by going fast enough to trigger the time travel. This platformer does things with time travel that few games accomplish. This game is perhaps Sonic's magnum opus.

The game might be too involved to Sonic newcomers.
