Here's a detailed review of the museum:
The inspiration for Nintendo’s new museum came, at least in part, from an ongoing irritation for Shigeru Miyamoto. At a certain point every year, the Super Mario creator does a presentation for the hundred or so new staff that have joined the company. It’s an attempt to explain the core of what makes Nintendo a creative force.
“I talk for two hours,” Miyamoto said during a roundtable interview ahead of the museum’s opening. “And after 20 years, I don’t want to do it anymore.”
...
Even worse, there’s no mention at all of who made any of these important works. Aside from Miyamoto’s signature at the front door, I didn’t see a single developer named anywhere in the museum.
The museum features various playable games, some with giant controllers, including Pilot Wings, which uses a giant Wii remote. You can see it in action at 13:40:
