Well, it is developed into that, it should have this:
Sonic, Tails, Knuckles, Dr. Robotnik, Flickies & the other animals you save from Badniks. It should be longer than Sonic 3 & Knuckles. The Super Emeralds should come back. Chaos Emeralds-Super Sonic, Semi-Super Tails (No Flickies (Lightning Yellow)), Super Knuckles (Fur golden). Super Emeralds-Hyper Sonic (Stars should spin around him, like the planet Saturn's rings), Super Tails (Golden-brown fur (With Flickies)), Hyper Knuckles (Hair stands up (Hair will repeatedly go golden-brown & yellow). The Death Egg should come back. Classic special stages like Sonic 1/2/3 & Knuckles. That's all the ideas I have for now.
