Man, this game really is fun! I just made it to the third island and I'm still having a great time with it. There is something just really fun about zipping through the open world areas as you open more and more of each island and it all starts to connect. It's just fun to grind those rails and traverse the islands opening it all up.
Even the action stages aren't that bad. They're a tad too easy maybe. I have been getting S-Ranks with remarkable ease in this game, but I'm still having fun with it all around.
The Super Sonic boss fights are fucking awesome to boot! My only complaint is I wish they were a tad more challenging. It does feel like the Parry mechanic was a bit of an afterthought. It's less a parry and more a deflecting block since you don't have to time it.
On the one hand, I kind of wish it had a little more challenge but at the same time I do kind of enjoy that it's not overly taxing either.
The combat system is surprisingly fun in this game but again, feels like it needed just a little more polish.
I love the SOTC style boss fights in this game as a whole. But I'm just a sucker for SOTC in general so of course they're right up my alley.
I can live with the pop-in issues. I mean, in some ways, they're giving me SEGA Saturn flashbacks.

The game has a really great sense of speed and fluidity to it but it's clear the engine can't keep up rendering it all. Maybe they'll improve it in the sequel. Still, the pop in isn't bothering me.
Yeah, this game is truly surprising me as to how much fun it is to play. This is a pretty damn good Sonic Team game in its own right. Yeah, it has potential to be better with more polish but they did a pretty fantastic job with this game and I've been having an absolute blast with it! It feels like a good blend between the freedom of control in the Sonic Adventure titles and the Boost games
@Spaghetti That said, can't help going back to it. Best comparison I've seen is weirdly to the Tony Hawk games, where there's like a hypnotic, rhythmic quality to playing that you just don't get by watching it.
It's funny you mention this. I've been getting a very Jet Set Radio feeling from it personally. Which kind of makes sense for Sonic.
