I'm currently playing through Hyrule Warriors Deluxe Edition's Adventure Mode Maps. Working on getting as close to 100% as I can be bothered to manage - it's very repetitive, but I'm honestly enjoying myself a lot. I'm an especially big fan of how the alternative costumes are all references to various games across the series (Ruto will forever use the costume that gives her Lulu's outfit).
I've played Hyrule Warriors a chunk on the Wii U, a whole heap on the 3DS version already, but the Switch version has definitely taken the most of my time!
As for other Zeldas, I'm also beginning a play through of The Legend of Zelda using the Switch's NES software, because it's there so why not?
