GamesBeat interviewed the producer for Genei Ibun Roku #FE (Shin Megami Tensei X Fire Emblem), Shinjiro Takada from Atlus, at E3 2015 today.
In response to how the collaboration project between Atlus and Nintendo debuted, Takada stated that the idea started when Atlus was working on a Nintendo DSi and Nintendo 3DS photo booth application.
I’m not too sure, since this all happened a long time ago. But the way it all started, Atlus was involved with Nintendo when we were making a purikura [Japanese photo booth] app for the Nintendo DSi and the Nintendo 3DS. Then there was a conversation that started about whether Atlus might be in charge of making a new Fire Emblem game,” Shinjiro said. “It wasn’t anything serious at the time. I think we turned it down at first because we had too much on our plates.
Genei Ibun Roku #FE (translated as Illusory Revelations #FE) will be released in Winter 2015 in Japan for the Wii U. It has recently been announced for release in North America in 2016.
