My Sonic Gameplay feature idea

Now, I will express this idea of a Sonic game feature I thought up.

Remember those alternate routes you took in Shadow the Hedgehog that lead you to different levels depending on what mission you took?

Well, without the use of missions of getting to different levels, I had an idea that is branched off of different paths you take as Sonic in the next Sonic game.

You know that in Sonic Unleashed, there were shortcuts and more than one path to take in any level?

Well, for the next Sonic game, how about there are different routes/shortcuts near the end, with each one having a different goal ring that will lead you to a different level than the goal ring that is on the main route takes you, just like in Shadow the Hedgehog, but without the need for those brain dead missions.

Unlike in Shadow, where the number of alternate stages after each stage increased, the number of stages after a certain point in the progressing of the game (with one stage you can get to depending on what goal ring on which alternate path you get to), the number of stages will decrease to the point that like the first stage, there will be only ONE last stage, regardless of what goal ring on what alternate path that lead to it you took.

Plus, regardless of what path you take, the story will not split and be complicated, but will stay simple, unlike in Shadow the Hedgehog.

What do you think?
