Genki Rockets
"Child of Eden" was developed by Q Entertainment. The game's concept was created Tetsuya Mizuguchi, who had worked at Sega on multiple projects including "Space Channel 5" and "Rez", the latter earning a cult status due to its graphics and music. After leaving Sega in 2003, Mizuguchi co-founded Q Entertainment and went on to produce the "Lumines" series, beginning with "" in 2004. During this period, Mizuguchi also created Genki Rockets, a music group to create music to his tastes, with their first major project being the music video "Heavenly Star". The reception to "Heavenly Star" prompted a live concert for Genki Rockets, and its mixture of visuals and sound inspired Mizuguchi to create a new project based around Genki Rockets and its fictional lead singer Lumi. The title shares several elements with "Rez", and Mizuguchi described it as a spiritual successor. He described "Child of Eden" as a chance to develop multiple ideas that needed to be left out of "Rez" due to technical limitations or was not satisfied with. As with earlier titles, Mizuguchi wanted to promote a feeling of sensory immersion, encouraging a form of synesthesia within players. Production began in 2008.
