So here I was ready to put Wances and Gronzit into my Adventure Game Collage when it hit me: Surely under our definition of the Empty Vessel Game it would apply? With "Telltale Games" as a format in which seemingly any IP could be applied too, but is not an on going franchise of it's own? That's the definition we laid out for Musou so there's no reason why it wouldn't apply for 'Telltale's'
So it's on the list! But also since that post I've played one game from the other examples we laid out; Mystery Dungeon, LEGO and Musou included!
