This is because Sonic is in the past at these points and the only ways to save the game are to either complete an action stage or obtain the Crystal Ring. On the first playthrough of the story Super Sonic has recap summaries just like every other character, but due to Super Sonic's story never saving after cutscenes, only two of them can ever be seen. It was later re-released with added features on GameCube and Windows as Sonic Adventure DX: Director's Cut. It's still considered a good game, despite it having aged pretty badly in many ways (like the in-game cutscenes and Big's fishing sequences). Sonic Adventure is the first true 3D Sonic game, with people either saying this killed the series or resurrected it. This game has unused playable characters.
