If you’re in Europe, you won’t be playing The Legend of Legacy alongside North Americans. Atlus’ JRPG has been given a 2016 release window. NIS America will release it both physically in stores and digitally on the eShop.
This is something of a tradition for Atlus games. The European releases tend to trail behind the North American ones. Shin Megami Tensei IV came to Europe on October 30, 2014, over a year after the US release, and NIS America still doesn’t have a definite launch date for Shin Megami Tensei: Devil Survivor 2 Record Breaker.
North America will be getting Legend of Legacy in Fall 2015, though Atlus has yet to provide an exact release date for the $39.99 3DS game.
