Is there a way to disable a victory type in a game that has already been started? Like some sort of file hack? I was playing my game and having a good time when suddenly I just won because of victory points. I was hoping to win by domination or elimination. I suppose I could just keep on playing.

When I first set up the game I didn't know "victory points scoring" was a way to win the game.

You could try Gramphos' MultiTool. That might be able to do it. Go to the Creation and Customization forum, and find the Utility Programs subforums. It has it's own thread there.

Otherwise, I know of no other way to do that. If you have your world seed in C3C (maybe PTW too) you can extract that from the conquests.ini file and restart your game using that. But then, I've never tried that, so I don't know if you'd start in the same place again.
