Two things Nintendo have made that arn't video games (excluding cards duh)

[DoesWhatNintenDont]

Well like Raccoon asked they do have a lot of officially licensed merchandise like hats, shirts and such. With the official emblem I would say it counts, regardless if Nintendo just gets royalties while other companies make the product themselves. ( I.E. Outsourcing.)

I myself have a Nintendo NES Wallet, but again it would fall into the merchandise quandary.
