The head of Sonic Team Takashi Iizuka has explained to Sonic Stadium that the immensely fun looking Sonic Lost World wasn’t influenced by the cancelled SEGA Saturn game Sonic X-Treme. Lizuka said that the game wasn’t at all influenced by Sonic Extreme and that the development team for Sonic Lost World don’t actually know about Sonic X-Treme, so it’s all new. Many Sonic fans have pointed out the similarities between Sonic Lost World and Sonic Xtreme, but Lizuka denies that there is any relation between the two.
“No. Not at all. Actually, the developers of this game don’t know about Sonic X-Treme so it’s all new.”
