So... I tried Hyrule Warriors: Definitive edition today.
My first impression is not good. I mean I was expecting getting nothing already but I was expecting a little more tweak to allow using the switch. You aren't even allowed to take videos.
The Era of the wild outfits for Link and Zelda are unlocked right away, so I tried to redo the first mission with Link in his BotW costume and watch the cutscenes with Proxi and the Fragment of the Triforce resonating. They both defaulted to Link as a knight Trainee outfit.
Now, in my WiiU I remember the outfit changed accordingly so this got me not only off guard but actually bothered me. I am hoping that at least the other outfits like OoT Link and such still work in the cutscenes and that it is only this BotW outfit the one that doesn't. Many of us want to see our outfits on the cool cinemas so it is a let down.
Now, supposing only BotW outfits don't work, it just really show how much of an afterthought they were and how they didn't even feel the need to polish the product for the switch. Honestly, I feel kind of disappointed with that.
