Yoshihisha Hashimoto, the key individual behind the amazing new Luminous Engine, may have already left Square-Enix.
This speculation comes from website Square-Enix Origin, which picked up a message on Hashimoto’s personal Facebook account. This message is a post from one of Hashimoto’s friends, who wishes him well in his new company.
Hashimoto was once a part of SEGA and worked on the Sonic the Hedgehog series for a brief time, most notably the Hedgehog Engine which was first showcased in Sonic Unleashed. He then went on to work for Square-Enix where he spearheaded the creation of the Luminous Engine.
