Mr Puggsly said: I don't think any of those games are spin offs. They are Sonic games. Some real spin offs are Shadow the Hedgehog, Knuckles Chaotix, Tails Sky Patrol, and that Dr. Robotnik puzzle game. |
Well I'd consider the games below as the main series:
Sonic 1, 2, 3 and/or Knuckles, Adventure, Adventure 2, Heroes, 06, Unleashed, Colors, Generations, Lost World.
Sonic & The Secret Rings and Black Night are part of the story book series
Tennis, Racing, Mobile, and the Olympic games speak for themselves. And I just consider 3D Blast a spin off.
