Dominion condition win? What's up?

[Etaoin Shrdlu]

In which case what if the victory threshold for amount of dominion necessary was set higher than (20* number of provinces on the map)? I know, I know, that's hideously unlikely (except by accident, like someone forgot that there weren't enough provinces for a dominion number of 4000 (the scale tops out less than that though ...?) ) Would that make the game unwinnable by that condition (although if you wiped out the other nations that would be end of game anyway...)?
