Snipperclips 2 years ago at the launch of the Switch. I'm not asking for a massive-budget AAA epic. But Nintendo can do more to work with Western AA developers to produce Western-made AA first party games on the Switch. Next Level is a good candidate for one of these.
Snipperclips is a low budget indie game that was being developed as a flash game.
As for giving one of their Western devs a shot at a "AA" IP ... I mean it's been a long, long, long time.
The last one I can remember was Geist for the GameCube. After the N64 gen and Iwata taking over in 2002, Nintendo started to cut ties to a lot of their Western partners (Rare, Left Field, Silicon Knights, Factor 5, etc.) and Retro has basically been a 1 game studio (Metroid or DKC) since, when that wasn't the original intention of the studio.
