This is an anecdote from a real game I played. Party walks into a room and all of the doors slam shut. We can't get them opened again. There is a big display on the wall showing numbers counting down from 10. There is also a big button next to the display. There is nothing else in the room. When the button is pressed, it resets the counter back to 10.
We spent a huge amount of time using all sorts of resources trying to figure out how to get out of the room, all the while pushing the button to prevent it from reaching zero. We weren't high enough level or properly equipped to blast the walls or dig our way out.
Finally, after much debate and argument, and not having any other ideas, we let the counter go, and resigned ourselves to whatever horrible fate awaited us. So, after all of that, what happened when the counter reached zero?
The doors opened.
