Horrible awful double posting, but I want to lay it out in general terms of origins:

VITAL:
Space America
Space USSR

Very Important:
Space China
Space Japan

Quite Important/Would be nice to have:
Space British Commonwealth
Space EU (such as it is)
Space Germany
Space South Americans (Andean)

Useful but not essential/can be NPC'd:
Space Italy
Space Scandinavians
Space Arab League
Space Korea

Most of the ones called out so far were generally smaller powers or client states, and thats fine, we do need a wide spread - and situations are subject to change. I may end up opting for space USSR, but I'm not entirely sold on it as of right now if someone else wishes to go for it. I'd like to get a few of these and serious discussions about anything people are worried about before moving forward.
