So after reading the first quarter of the book, it's definitely a great start for reference books regarding Sonic. Future Some reference books could expand on Sonic's TV career. They mention AoSTH and SatAM briefly in the 1993 section. The other ones, like the two japanese episodes, SU, and Sonic X had no mention (yet). There should definitely be more visuals of cut content from the games, especially Hidden Palace, Dust Hill, etc. Even if it were just passing mentions, it would add to the content, and show what could have been. Also, discography with Sonic music, that could add more padding to the reference books, lol. Or perhaps they're saving that type of material for a second volume...? Eh, who knows.
