How to change victory condition of an ongong game?

[Blkbird]

I know victory condition is set at the beginning of the game and never not supposed to be changed, but there must be a way to hack it, right?

The thing is, I'm playing against the AI on an easy level with default winning conditions and suddenly realize I'm steps away to archieve 35% world population, which would fullfill the Domination condition. Even though I know I can continue playing after I "won" the game, it would of course be much less fun then.

So please, can anyone give me some help please? I've checked the Ctrl-D debug dialog but haven't found anything. Maybe the World Builder would do the job?

From the world builder menu I found how to change the victory condition when designing a game, but how could that be applied to an ongoing game?
