Actually, new proof has surfaced that you can find Rupees within the World of Hyrule as well.
So that's cool, and that sticks to the tradition of having easy access to fifty rupees early game.
This is definitely not a common occurrence as well. But it is great to know it is there.
I think it says a ton that even though we have hours, and hours of footage. We are still learning things just from this demo alone.
I figured you could probably find rupees in things like treasure chests in dungeons and stuff, but it looks like some are in the overworld, too. Just not by cutting the grass it seems. Neat.
