This is where there is a chance to save Sonic from being the poster child of bad games.
The only thing we know for sure is that Sonic has hit rock bottom, now it’s his time to clean up his act. For instance, you can’t play a water level the same way you play an ice level because one is slow and the other is slippery.
The variety comes in levels instead of characters. Eggman is snatching up your friends so stop him-and the gameplay doesn’t suffer because of different styles. Sonic shines when it’s just him (or with characters that play similar). For whatever reasons, Sonic’s speed and level design do not compliment the camera very well. Another long running issue with the series is the camera control. The fun, fast Sonic or Tails levels get dragged down by the slower Big the Cat or Knuckles stages. Sonic Adventure is one of the first games that come to mind. Even some great 3D Sonic games suffered from these issues. In terms of gameplay, those characters screw up the natural flow of the game. For the story, the amount of furry friends makes the plot a mess.
One big issue is the amount of characters.
That’s why something like Sonic Boom just doesn’t work, there is too much going on.
