I would love for there to be more BDSM elements. Specifically, letting your character end up in the open world exploring with their hands tied behind their back. It would restrict a lot of features from being available until you can escape.
It's pretty unlikely as that would need to be accounted for everywhere (same reason why you can't bring partners out of their designated areas.) I could certainly see about 'escape maps' though, where you're captured and tied up in an area and need to escape.
