The 'altruistic victory type' remembers me the Star Trek's United Federation of Planets!!
It's a good idea but I think this is really unrealistic.. I preferr the 2050 time limit; that has no historic mean but it's necessary to 'cut' virtually unfinishing games; it's a problem of the player to play doing something tricky in the last turns or not. I really dislike tricks and my behaviour in the last turns is to play as if the game continues over 2050..
I agree with tmarcl: very interesting a mix of independent new civs and puppet civs.
Another think is regarding the opposite to liberation: the burst of indipendence war in a city.. The indipendence wars are a costant of modern age and in Civ they simply don't exist!
It's simple to image the parameters interested in a 'casual' declaration of indipendence of one of player's (or AI's!!) city:
- distance from the capitol,
- number of cityzens,
- number of culture points,
- if the city is on another continent,
- if the city has a Wonder (that unites the people around a 'national symbol');
it's thinkable that the cities around the rebel one join the rebellion..
PS: Sorry for my english!!
