I would like the entire map to be revealed after 2 or more civs discover Space Flight. I don't mean that you have to see units, or improvements, just the terrain. By this stage of the game everything you can exploit to a significant advantage already has been discovered, so there is no real advantage to the player. It's always annoying to me, though, being in the Modern age, with advanced planes, AEGIS cruisers, and still having all those little uncharted blotches on the map.
