I m hoping that, besides being able to shut down 'Victory by UN' completely, that the victory conditions will be modifiable through the editor as well so we can adjust how much land/population we need to be a part of the council.
-edit-
I just had a brain fart!
In SMAC, everyone could vote to elect what was known as the Planetary Governor, and ultimately, the Supreme Leader (which gave that player a diplomatic victory).
I was just thinking- what if when Firaxis said you need 25% of the total land, or 25% of the total population to be on the UN council, what they meant was that you needed those numbers to be a
candidate for World Leader, but everyone else
still gets to vote?!
In SMAC, only the two players with the highest population counts were the candidates for Planetary Governor, but everyone else did get to vote.
Now THAT makes sense!
