Well, dragons are impossible is a quite logical in-fiction state of affairs, but the rules of D&D preclude it. So we have to come up with other fictions!This last is suspect in a follow-the-fiction sense, in that oftentimes "nothing happens" would be a quite logical in-fiction outcome.
Likewise in Dungeon World - the GM must come up with something else. That's part of their job.
Those are not things that will happen in a game of Dungeon World. In fact, none of them actually triggers a player-side move, and in each case the GM would be obliged to say something - by default, a soft move - in response.I try to open a stuck door and fail, nothing happens. I say I'm giving my contact an hour to appear and then leaving, nothing happens during that hour so I leave. I speak to a statue, nothing happens. I'm running surveillance for the day but I fail because my target never appears, so nothing happens.
