What does the term "endgame" refer to when used in the context of politics?

I'm assuming it just means the final stages of, say, passing legislation.

Remember the day the Berlin Wall came down?

Did you hear about the fall of the Roman Empire?

It means something is coming to an end, and at this point people are just maneuvering to brace for the impact.
