"I've played this type of open-world game before."

No, you haven't. Just one example: A game where every mountain and every tree is interactable? Where when you shoot an arrow and miss, it persists in the world? Compare BotW to the other open world games that were popular at the time of its release: Witcher III and Horizon Zero Dawn. None of them do this. The closest is maybe something like Oblivion, where you can climb the mountains, but not the trees and you're not soaring through the air on a glider. And BotW did it on Wii U hardware.

You don't have to like it—your preference is your preference. But if you don't understand why it's considered revolutionary, you're either not thinking or you just don't know as much about video games as you think you do.
