I've been thinking about refinements to the spaceship (exploration) victory.
As far as I can see, there's very little to it right now, and it's sort of broken.
The victory right now involves finding the new world as the ultimate ends... while this makes sense for the Western Europeans, it makes little for either of the med or islamic civs.
So I've been thinking of the possibility of two or more different spaceship victories...
my inquiries, as yet unanswered, are in this thread...

Anyhow, if more than one spaceship victory is possible, I'd think, due to the differing goals, and end positions of the different civs, these are possible ones...
-Establish permanent colony in the new world
(this is for West European civs)
-Establish trade embassy with China
(this might be for Mediterranean Civs), and Maybe SW Europe/North Africa
-Secure the Silk Route
(this would be for civs astride this route like Persia or the Turks, and maybe Byzantium)
Things like founding a series of colonies in different places, or establishing trade missions along a route, or providing valuable gifts to various Monarchs along the way would comprise the modules and components of the "spaceship" in varying numbers.
Of course all this is moot if more than one spaceship victory cannot be created.
Nevertheless, creating some number of colonies along the West African Coast could be attached in lieu of spaceship parts to that part of the Exploration Victory, and similarly for the other stages...
Naturally, the spaceship victories should be equally difficult, though different... perhaps Spice Resources might be needed for creation of a series of Indian Colonies, for instance, while Silk might be needed for an equal number of Trading Posts along the Route. Equivalent in Tech required, and in needing a resource, but differing slightly in substance.
I'll refine the idea further when I've more info.
