Yuji Naka
Sega Technical Institute (STI) was an American development division of Sega. Founded by Atari veteran Mark Cerny in 1991, the studio sought to combine elite Japanese developers, including Sonic Team programmer Yuji Naka and his team, with new American talent. STI developed games for Sega Genesis, including several "Sonic the Hedgehog" games, before it was closed at the end of 1996.
