The Legend of Zelda: A Link Between Worlds notably lets you play dungeons in any order, thanks to the ability to rent and buy items instead of finding them in dungeons. In case you're worried that will throw off the difficulty ramp, producer Eiji Aonuma has thought through that problem and says it won't be an issue.
"In terms of the difficulty level, each dungeon features new ideas involving the item you need to use there, so there isn't some kind of process or order you can follow to make it easier," he said. "However, if you are using a particular item more than normal you will become more used to it so you may find it easier to complete the corresponding dungeon in that case. However this is a reflection of your own skills increasing so I think the game would be most fun if you try out lots of different approaches."
Weapons are also upgradable, and he said he finds the bow particularly useful since it can fire three arrows at once. He ended on a note that the team hasn't forgotten about Majora's Mask, and hinted that A Link Between Worlds will have some kind of Easter egg for Majora fans.
