Mania Sonic is NOT Classic Sonic

I'm theorizing that Sonic Mania can't take place after Sonic 3, but really, in fact, takes place during it. To be precise, Sonic Mania and Sonic 3 are in different timelines. Sonic is whom decides if it's Sonic 3 or Mania. Here's my reasoning.

First: Countering the elevator claim

If you don't know, the opening and Pre-Order trailer have an elevator that is labeled based on Sonic games based on release. 1 for Sonic the Hedgehog, 2 for Sonic the Hedgehog 2, 3 for Sonic 3, K for Sonic and Knuckles, and M for Sonic Mania. They aren't in chronological order, since Sonic CD is missing and it seems to take place before Sonic 3/Mania. Heck, before Sonic 2 since Sonic seems to be still learning the Spin Dash.

Okay... let's compare the intros for evidence. First, 3. Sonic is riding on the wing of the Tornado and jumps off, turning Super. He skims on the surface onto the shore and is stopped by Knuckles, losing all 7 Chaos Emeralds in the process.

Sonic Mania starts the same, except Sonic never goes Super. When he goes on shore, he skids to a stop, seeing the Robo Eggs.

Sonic never goes Super in Mania so... he doesn't have all Chaos Emeralds. Actually... he has no chaos emeralds. In every Sonic game where Chaos Emeralds are a thing and there are intro cutscenes, we see Sonic lose the emeralds. Take Unleashed, where Super Sonic is trapped and the energy is sapped from the emeralds.

I'm theorizing that Sonic Mania happens after Sonic 2, when Sonic doesn't get any Chaos Emeralds. Eggman got a hold of all 7 and got the Master Emerald. He found out about a mysterious gem on Angel Island called the Phantom Ruby. He sends 5 Egg Robos to collect it as Sonic and Tales got there. They got the Ruby and used it's ability to travel through space time to warp Sonic, Tails, all 5 Egg Robos & Knuckles to Green Hill (Yes, I had to make an & Knuckles joke). Another thing to note is that, like Sonic 3 & Knuckles, Knuckles accidentally gets roped into the brawl.
