So they're aiming for another Zelda title before the Switch ends. That's awesome news ^^
I hope they keep the formula from BotW, that being said what I really missed from the older games were the dungeons obviously. Proper dungeons this time. And also environment variety in all closed spaces. All we got in terms of closed spaces were shrine type, dungeon type and Hyrule Castle (which looked awesome btw).
Also what I regret they did not do was a good number of caves and underground galleries, some of them interconnected, that are part of the overworld not a dungeon. They have not really done that in any 3d Zelda game with the exception of Twilight Princess maybe as it tried something like that in its overworld design. The caves in Link to the Past were awesome, some of them were actually shortcuts, some of them more like labyrinths and others more like trials. Well, pretty much like BotW trials come to think of it. It would add variety to the environments and the exploration in general. Also in a lot of games they serve as optional content with really dangerous bosses hidden inside.
I'd all over a Zelda title that could be smaller in size but have multiple layers thanks to underground spaces.
That being said I wouldn't mind if they flat out kept the same map but actually ADD underground and closed spaces. Maybe the same map but in another time period. Everyone is dying to see how the kingdom was before the apocalypse, and with the number of wiped-out villages and places, and fortresses that we see but cannot enter, I would imagine the map would be barely recognizable anyway. It would be a great way to save development time and still keep something of the same scope, even bigger and with more density this time around.
Okay that turned out to be a wall of text. You're welcome Nintendo.
Anyone's got Aonuma's email adress ? ^^
