I am almost done with Echoes of Wisdom and thought the map was the perfect size for the game. I always felt like Breath of the Wild’s map was too large for what was offered. Tears of the Kingdom kind of made that worse by doubling the map underneath and having it mostly be empty.
I like TOTK’s map. It’s not really the activities there are to do in the map, but the sights. BOTW, with the same main map, is good but you had very few traversal options, making it too big. But you can literally build a helicopter in TOTK and fly everywhere, so you can actually explore it in a more timely manner.
The floating sky stuff was more disappointing than the underground, personally.
