Nintendo isn't a stranger to the small screen. There have been a handful of Nintendo based cartoons and Animes: Mario, Donkey Kong, Zelda, Kirby, F-zero, even a fire emblem ova. The question is which Nintendo IP could actually be successful as a full 12-26 ep anime?
Not simply what you want but what would actually be a success financially for Nintendo.
Poll was added so I wouldn't have to do two threads. It's a different question. Which ip would be successful that hasn't already been done?
