Escape shuttle is weird. So what makes a good round end?

Ss13 is a multi-player sandbox space station insanity simulator with no clear goal on most rounds.

The escape shuttle exists to call an end to the round and let everyone shuffle around their roles and keep the game from stalling out.

There can be no defined end because there is no defined purpose. I don't think the game would benefit much from adding one.
