[Baron Munchausen]

I suggested something like this long ago in the beta process. I called it 'ascension' and it's very easy to implement. Just have a 'special' location for population to migrate to when certain conditions are met. (Sufficient tech levels, sufficient cultural advancements, etc.) When either a certain percentage or a certain flat number of your population have migrated to the 'higher plane' you win. And it uses an already existing feature of the game! Yeesh, how much easier could it be to add a cool idea. But no, no one else seemed to like it.
