It wasn't until a recent replay that I realized how much I really enjoy this game. I think if you're coming off of playing Sonic 3, the movement in this game can really throw you off. Both the controls and the general pacing of the levels feels more akin to the first Sonic game. For some, that might be an instant negative. But I feel as though CD takes some of the slower paced platforming of the original Sonic and builds some more engaging levels out of it.

This game also has a unique approach to the typical Sonic appeal of replaying levels. You want to master these levels, not necessarily to complete them as quick as possible, but to make sure you get the Good Futures. The Special Stages are also pretty fun, tied as favorites with Sonic 3's.

Not all stages are winners but Sonic CD more than makes up for it with its ambiance. The JP soundtrack and the Past / Bad Future levels give the game a particularly eerie feel that none of the other Genesis titles can capture. It's a statement to how a game's tone can elevate the whole experience.
