Trivia: Sonic Lost World
- Ascended Fanon: On a marketing scale, while the Japan dev team did not actually rely on the Sonic X-treme project for materials and inspiration, the fans have noticed the similarities, and Sega of America appears to welcome the comparisons.
- Development Gag:
- The Deadly Six Edition features bosses from Ni GHTS Into Dreams. Sonic Xtreme was going to feature bosses designed with the NiGHTS engine, which could be one of the few intentional references to Xtreme's development.
- Sonic knocks billiard balls into their holes as he rolls around whilst entombed inside a giant snowball in Frozen Factory. Believe it or not, there was a billiards mini-game in one of the many scrapped Sonic games from the mid-1990's, where Sonic had to act as the cue ball.
- Fan Nickname: SLoW (Sonic: Lost World).
