1. Sonic Adventure 2 evolved a lot, originally neither Rouge, Shadow or Tails were playable but the fans demanded tails to be playable so they basically gave him the controls and gameplay of Dr.Eggman, but there is also a theory thats says that tails was going to be playable using his chao garden controls(in the chao garden Tails can fly, drown and attack) but they ran out of time.
Shadow was named Terios, Rouge was named Nails and the story was going to have a morality system that was later used in Shadow the Hedgehog.
4. Sonic Mega Collection and Sonic Gems Collection both were originally going to have Knuckles Chaotix in them but couldnt due to emulation problems.
5.Sonic Heroes"s Team Dark third member was originally E-102 Gamma but since Sonic Team couldnt find a way of bringing him back without being too ridicioulous they instead created E-123 Omega.
