Concept: a Legend of Zelda game where the “dungeons” are part of an ancient Hyrule-wide defence grid that’s been corrupted by Ganon’s magic. While Link goes about doing his thing, Zelda is holed up in a fortified shelter under Hyrule Castle that serves as the network’s command centre, and it able to remotely manipulate each dungeon’s layout, as well as the surrounding geography once full control of the dungeon in question has been reestablished.
Gameplay would involve flipping back and forth between Link doing his usual thing, and Zelda god-moding the terrain to solve higher-level puzzles, with ample opportunity to accidentally squish Link or drop him into bottomless pits or whatever if you screw up. Or, you know, just for fun. It’s okay – he gets better!
Additionally, early on Link would pick up a cute little drone that Zelda can teleoperate when a more direct hand is needed. It’s not combat capable, and to start with it can only flip switches, fit into small spaces that Link can’t, and be thrown by Link to deploy it into unreachable areas, but there’d be a series of upgrades over the course of the game that let it plant bombs and teleport and such. There’d be puzzles that would specifically require repeatedly switching between Link and Zelda (teleoperating the drone) to open paths for each other, Lost Vikings style.
(I would like to claim that this concept is meant to explore ways to give Zelda a more active role without just turning her into an ersatz Link, but in all candour it’s mostly aimed at manufacturing an excuse to have Zelda at some point say <hackervoice>”I’m in.”</hackervoice>)
Link: you can see me, right. Link: tell me what is wrong with this picture.
