I would think I'd allow very diverse and multicultural Nations. 1 or more Species. Nations of subspecies of another Nation, etc. I suppose with this NPC Nation that likes swarming active-fighting Nations could create a story. Ever since their arrival, it has put Nations on edge of attacking each other, as the NPC Nation was a mindless, animalistic hivemind, which could savagely slaughter unarmed/unarmored species. With this in mind, all the major and well known Nations resorted to spying on each other. And even when caught, a spy being caught would act as mockery or insult to the spied Nation.

There will be ... I think, 4-6 large Nations, with max technology and attack power for the time in this roleplay (Max level, in comparison to thinking they were "super powers," but they aren't exactly "super") And then I will allow multiple smaller Nations. Now, what I mean by small, I mean, trade off Nations. They can have a large population, but low technology, or they can have a higher level of technology, with low population. This can work out in many ways, for example; refugee's, fleet-bound nations, explorers, settlers, etc.

Ah, on that point, everyones' travel technology should be relatively the same. In this, I mean, nothing that lets you teleport to one side of the galaxy to the other. More like; teleport a quarter of the way, haha. But I wouldn't be against "custom travel engines," in that, I mean, the look and feel of engaging the engines. I'll put out some examples. Blinking, just pure blinking, if you understand. Travel with so much inertia you you need to strap all members in a ship down. Or, maybe this spacial looking aura/blanket (Similar effects of a shield) swallows the ship and it begins to light up as it then shoots off, out of sight.

I might be thinking of... the lesser Nations not having warp or hyperdrives. I mean, the ones that did not trade off for technology. It is still possible to be a larger populace with space ships. And it will be possible to trade technology, as long as you can cross the language barriers.

I won't do some sort of point system. If/when I can get some Co-GM's, they will add to a private vote with me on if a Nation fits the bill.
