But these games are regarded as continuity than specific series such as Adventure or Storybook games. Yes the Adventure games are also part of continuity but they are recognised as a series by their gameplay. Which is why I think when fans ask for a "Sonic Adventure 3" they specifically want a Sonic game simply with Dreamcast like gameplay.

Also, is Sonic 4 is erased somehow, it stands to reason that Eggman would still revive Metal Sonic anyway and he'd go on for his role in Knuckles' Chaotix, Sonic Triple Trouble, Sonic the Fighters, Sonic R, Sonic Adventure (where he's shown apparently being modified into his Modern appearance), Sonic Heroes, etc. I don't believe Sonic CD takes place between the episodes of Sonic 4.
 * Being seven years apart, the art style of the game is vastly different from one another, such as Classic and Modern characters.
 * The plot on the official website says Episode 2 takes place a few months after Episode 1. Little Planet appears over Never Lake one month out of every year, and vanishes completely for the remaining eleven months. This rules out the possibility of Sonic CD taking place between episodes since there was a few-month interval between episodes while Little Planet appears annually.

However, Episode 1 did say Sonic and Tails did part ways after Sonic CD, so it could be possible Sonic CD takes place after Sonic 3&K, despite Sonic sprites being from Sonic 2.

Not entirely sure where games with questionable continutity such as the MS.GG games, Sonic Battles or Sonic Chronicles stand.
