I think there's hope.
SEGA/Sonic Team didn't learn any lessons from the crunch and unreasonable time windows forced on their dev teams. Each game comes out feeling unfinished and buggy (to varying degrees mind you).
The game still sells and despite middling to poor reviews, a contingency of Sonic fans will loudly proclaim that a buggy Sonic game rushed out by an overworked team is "so much better than people realize" and "people only say they dislike it because hating Sonic is trendy".
The cycle repeats.
Sonic Adventure (1st edition).
Sonic Heroes.
Shadow the Hedgehog.
Sonic & the Lost Rings.
Sonic & the Black Knight.
Sonic 06.
Sonic Genesis.
Sonic Riders sequels.
Sonic Unleashed.
Sonic 4.
Sonic Boom.
Sonic Lost World.
Sonic Forces.
I don't think these are objectively bad games, not at all. But they are all deeply flawed in different ways and most of them were rushed out the door, sometimes with reduced teams, to meet a deadline that SEGA refuses to loosen. Horror stories from behind the scenes at Sonic Heroes, Sonic 06 and Sonic Boom helped me understand why those games came out as sloppy as they did (one game obviously not being as bad as the other two) and gave me a lot of empathy for the people who are trying to make these games happen.
So what changed?
COVID-19.
2020 was supposed to be the Year Of Sonic. SEGA promised that a new Sonic reveal or announcement would happen every month of the year. With the pandemic, the Sonic SXSW event was canned and SEGA announced that the Year Of Sonic was pushed back and they needed more time to work on titles.
From history, SEGA taking more time to let developers polish a Sonic game isn't a common occurrence.
My hope is that the extra time and polish leads to tighter final product.
