Nintendo seems to be publishing The World Ends with You: Final Remix in the west
Nintendo and Square Enix have formed a fairly close relationship in recent years, particularly in the west. The Big N has long published Dragon Quest games on its platforms in North America and Europe. Additionally, Nintendo will be in charge of Project Octopath Traveler’s release in the west.
The World Ends with You: Final Remix appears to be another Square Enix title Nintendo will publish in North America and Europe. The official North American and European website pages indicate as such. Nintendo also had its name listed for The Worlds Ends with You segment in the English Nintendo Direct Mini whereas the Japanese presentation had Square Enix.
So that’s an interesting little tidbit. Square Enix originally published the DS version of The World Ends with You in the west, but it looks like that duty now falls to Nintendo for Final Remix.
