Terraria, the Minecraft + Metroid mash-up, may be the next major indie game to find its way onto Nintendo platforms. GameFly has listings for currently nonexistent Wii U and 3DS ports, both with a tentative release date of October 31, 2015.
Terraria is already available on just about every other gaming platform on the planet, from PS3 to 360 and even Kindle Fire. In the last couple of months, it finally arrived on PS4 and Xbox One as well. Some Nintendo representation wouldn't be completely unusual for a kid-friendly game like this — disregarding the case of Minecraft, that is.
We'll keep you posted if anything new develops.
