You morons are all missing the point about Dream Team.

The only reason this game is even remotely good is because it's the most windpilled concept we've had in years and it finally, FINALLY, gives Cream the respect she deserves. The entire plot is centered around her.
This is the first time she's been this important since Advance 2.
She's a younger female Sonic who fights for justice, not just some polite damsel. She stands up to Eggman and is ready to fight.
She's an exceptional civilian who rises to the occasion, proving she's just as capable as the core 4 (who really should be the core 5).
That's why she's a great character. She's VVIND.
And the setting itself? A dream world where reality is twisted and you can shape things with your mind?
It's the perfect playground for Windnic. It's literally "the power is in your mind to shape the planet to conquer time." Sonic is an ideal, a force of nature who can do anything. A world made of thought is where he would naturally thrive. The level design focusing on flow state, rollercoasters, and half-pipes is just a bonus that actually understands how Sonic should move.
But let's not get too ahead of ourselves. You know who wrote this? Ian Flynn. The archie-fanfiction hack who is undoubtedly a cancer on this series. The only reason any of this works is because he was forced to write a concept that is in line with Actual, Existing, Sonic the Hedgehog. He didn't come up with this out of a deep understanding of the character, he was given a great plot by Sega Hardlight and ran with it. I bet you anything he still doesn't know how to write Tails. Just the tech-support tablet boy again, spouting exposition like a Sally Acorn stand-in? Pathetic.
