Nearly four years. That’s how long Hyrule Warriors has been out, and very few people have probably 100%-ed it.
I don’t blame them! While the core loop is fun and the roster is on point, upgrading every single hero and villain and obtaining every key item for them would take hundreds of hours. I spent a few hundred of my own just working on a few of my favorites, and I’ll probably spend at least half of that on Switch with the Definitive Edition all over again.
