So it is pretty much assumed at this point that the Switch dock will detect when the console is inside through USB-C, which transfers data.
In that case it would be super righteous if there was a household adventure game. Like, while undocked, the game has you explore using AR, fighting monsters and collecting treasure, but the only way to keep your loot/progress is to find a "save point." A dock. Then they could expand the benefits a little bit, like, plugging your switch into a new dock unlocks gear or something, encouraging people to bring their switches to their friends' houses to plug into their docks.
