The Legend of Zelda

Sonic Team essentially split into 2 after Sonic 1. Yuji Nakka was feeling very dissatisfied with his position at Sega in Japan, so he went across to America. He basically got his own team filled with Japanese staff in America at the STI - which of course stands for Sexually Transmitted Infections. If there was a lineage there, it would have been inspired by Sonic CD rather than it being a direct continuation of what they're trying to do.
