Currently, Nintendo is one of the few developers in the industry who doesn't extensively use third party engine software. They've warmed up to its use in recent years though. Yoshi's Crafted World was built on Unreal Engine, and the launch title Snipperclips was made in Unity. But most of their games are still built on custom engines. That's not a bad thing necessarily, but with the Switch being so PC-like thanks to Tegra, it makes me wonder if Nintendo should leverage that more. Should they do more games in Unreal Engine 4 and Unity, especially with so many other Japanese developers using those engines?
