Back to the 'v' button.... What if it is one page showing the different victory conditions and where you currently are in completing them. In other words,
-you would have MapStat built in to show how close to Domination you are,
-Conquest could just show you how many Civs are in the world (not so helpful unless you are playing with a ton of them),
-Spaceship could just give you a quick summary of total number of parts completed for you and any competitors,
-etc.
Just a thought.
