No, we\’re not talking about Assassin’s Creed: Unity — it’s the Unity engine. This engine is popular with a lot of indie developers for its easy-to-use functionality and affordable price range. Nintendo knew of these facts, and made sure to secure a partnership with the company very early on in the Wii U’s life.
That partnership has continued, as the newest version of the engine — version 5 — will support Wii U, among several other platforms. This is naturally good news, as this means that more indie titles (and apps) will have the opportunity to easily be built and rolled out on the Wii U. Who can complain about more stuff?
