Sonic Team has a winning formula here. Great game. They can do a lot better.

Pros:

-Most character development to have ever exist in a Sonic game.
-"Open Zone" sandbox gives a ton of freedom to tackle things how you want to. Game doesn't hold your hand past the first 30 minutes.
-Killer sound track.
-Combat is simple and flashy, but engaging. Isn't a one button masher had depth that can be expolored with the skill tree. Skill tree even has an optional auto 1 button mode.
-Boss fights did DragonBall better than DragonBall.
-First Sonic Team game to have proper voice direction.
-Fishing mini game is both relaxing and a nice break from the action. It still benefits the overall game progression by playing.
-Ability to fine tune how Sonic moves by editing the turn radius, max speed, etc.
-If game ending is anything to go by, I'm looking forward to each character's development in the next Sonic title.


Cons:
-Character animation lacks emotion. The animators hold back with not animating something as fundamental as the characters' eyebrows to display emotion. They opt in on using the eye lids, which doesn't give off the same effect.
-Cyberspace levels are mixed to bad. Taking past level layouts is a neat idea, absolutely. But the idea falls flat when the Sonic game made with those levels didn't have Frontiers in mind. Expect to either run into a lot of walls or fall off on levels based on Sonic Unleashed / Generations. Stages based on anything SA2 or older work like a dream. Sonic is also pretty slow exclusively in Cyberspace and while in Cyberspace, his in air control is dismal to the point where it rivals Little Mac from Smash Bros.
-Floating platforms that contain obstacle courses and mini adventures feel like an after thought or a fan project. Sometimes, they look unnatural with their surrounding environment.

Spoiler warning:
-4th island isn't an island so much as its a set of obstacle courses required for the story. There's no collectibles in it. Once you pass it in the story, there's no incentive to go back.


Now for the meat and potatoes. Is this game a good PC port...?

No.
It's missing some PC centric features:
-Missing HDR support.
-No native ultrawide support.
-Render resolution can only go down in incriments of 25%.
-Game has a hard cap of 60fps.
30fps for curscenes.

It is optimized well in the sense I was able to have a true, locked 4k@60fps on a 2080Ti.

I had a ball, and this is a wonderful step in the right direction.

If I could change anything from this game from my cons list, it would be just the cutscene animations to push more emotion in each of the characters actions.
