I dunno, perhaps one may need to go to the 18th century politically here.

No UN, but trade was common and alliances still were forged.
[/quote]Well, this game is set in the future and they could do at least as well as we in the present.
But even disregarding that my point was that if it's a blind exploration game then there aren't any alliances or trade routes. Our player civs don't even know the other exits.
Which I feel would defeat the whole point of this setting.
