The best part of the Sky Box is how the position of the stars will coincide with the position of the Dungeon Corridors. Dungeons will literally change as the seasons change. So being able to see the stars will not only allow you to know when to plant and harvest your plants for farming with the seasons, but will let you know which corridors in the dungeon are open, and thus which boss is presently available. Hard to know what the party needs without knowing what you're going to be fighting in the dungeon. The dynamic aspect of Dungeons is VASTLY under rated.
