The Nintendo Museum opened up yesterday, and tickets are randomly picked lottery style. I honestly can't tell if they did this out of greed or they knew that this place would be extremely crowded as there are no plans for one outside of Japan.
Honestly, other than being in a former Nintendo factory, this place doesn't seem special at all. It's no different to a Video Game Museum in Texas that I've been to. In fact, I think they copied the whole "play retro games with giant controllers" from the giant Pong console in that museum.
