An interesting new take on the Sonic series that I'm very mixed on. It's fun to have a Sonic game that allows Sonic to run around a huge open area, but personally, the appeal of open-world games has always been the exploration. Sadly, exploration is not this game's strong suit since the design of the world itself isn't too interesting. Instead, it's more about coming across miscellaneous obstacles and completing them to get rewards. These were fun, and the way they all connect and flow into each other feels great, as it constantly keeps you moving. However, this core gameplay loop does get rather repetitive, so I had to take breaks often. Also, collectibles were usually ridiculously easy to get, so it was rare for completing something to feel truly rewarding. The cyberspace levels added some nice variety by having the normal Sonic gameplay, and the bosses/guardians were often really fun to fight. Overall, I wouldn't say this is one of my favorite Sonic games, but it's definitely a good one. I'm interested to see how this formula evolves in the future.
