Sonic Team
Sega Studios USA oversaw the development of "Sonic Rivals" (2006) and "Sonic Rivals 2" (2007) by Backbone Entertainment. In 2008, Sega Studios USA merged with Sonic Team, making Iizuka the head of Sonic Team and a vice president of product development for Sega. In 2016, Iizuka relocated to Los Angeles to oversee development with the goal of making Sega's studios in Los Angeles "a centralized hub for the global brand".
