I just found out that you can't build the United Nations if Diplo victory is off. This was annoying because I created a game specifically to play with UN resolutions but without having the game end due to someone being elected as the "winner", so I turned Diplo off. I beelined to Mass Media and then found out I couldn't even build the UN! Lame.
I wonder, if I went into WorldBuilder and added the UN to one of my cities, would I be able to have elections? Or do the elections not work at all if Diplo is off? I feel like you should still be able to vote on things like nuclear proliferation and certain civics and stuff even if Diplo is off...
I think it's just one line of xml code that needs to be modified to allow the buildings to be built but I don't know how the game would act.
