A solid foundation for the future but I don’t think that’s enough for a full price release with 6 years of development. The peaks of frontiers are some of the highest in the franchise but the lows are so bad and unpolished, updates 1 and 2 addressed a lot of issues I had but update 3 was absolutely awful and that makes me worried for the future of 3D sonic. The vocal themes are great but the music Otherwise is really forgettable.
