It certainly wasn’t incredible, but for Sonic a 6-7/10 is basically a 9/10 to hardcore Sonic fans. That’s okay, and it means the game inherently isn’t for everyone. It’s got lots of issues, but I think if you can look past the surface level details it has a lot that it does right too.
It’s definitely, from the position of a jaded fan who tried it after years of ignoring (and occasionally playing because they’re so bad) Sonic releases because of the poor quality, the best release in a long time.
