Yes exactly. A Zelda game where you play as Link, Zelda and Ganondorf in separate parts of the game would be very cool. Something that is canon and not Hyrule Warriors like. And not CD-i garbage.
What I read was you get 3 hearts if you've not beaten the cave but if you have, you get how many hearts are stored on the amiibo for the wolf in BotW. I'm not sure how correct that is though.
Was it specifically said by Nintendo that you have to complete the cave of Shadows to import wolf link into BotW? I'd like to know as I've heard something different.
