Yes.

Sonic got objectively worse except for a few standouts, yes

Sonic peaked at Sonic Spinball

:I-was-saying:

I kinda liked Sonic Adventure.

To be honest I don't find any of the Sonic games well designed whenever I go back and try them. His whole thing is speed, so things gotta move fast. Then there also has to be a challenge, so there's suddenly some obstacle the player has to react to, like a monster or spikes, but you're moving so fast that you don't really have time to react. Idk maybe I'm just too old and slow nowadays.
