A lot of people I’ve seen have wanted dungeons again, not everyone was a big fan of the divine beasts. Me personally, I want more of the same from the first game. I thought the game was just about perfect.
Two things that I can think of right off the top of my head, though, would be better climbing gear and weapons. I’ll dive into what I mean by that. I think that climbing gear that is difficult to obtain but would allow you to climb normally even during rain would be really awesome. My only other request would be a weapon of each type and shield that absolutely never break. So the Master Sword without the timer and the Hylian Shield without the possibility of ever breaking. I’m totally cool with the durability feature shown in BotW, but when we get to the end game it would be nice to be able to just kill everything without worrying about your weapons constantly breaking or your Master Sword running out of juice. It’s not a make or break thing, but it would be really cool.
