Love the concept, I just know I don't have it in me to roleplay a modern nation-state.

If you're not already familiar with it I would recommend looking into Serial Experiments Lain for a similar sort of "it's the 90s and computers can do anything" vibe.

I didn't wanna give the impression that you [i]had[/i] to strictly play as a modern nation-state. In fact, a few ideas for what you could play as alternatives come to mind...

[list]
[*] [b]Multinational Corporations[/b] - A lot of countries in our own world have incredible influence all around the world, to say nothing of the power they exert in their home countries. With the rise in disasters and relief efforts, there would certainly be a lot of countries with some deals to be made for food, medicine, and other essentials. Think of all the advertisements we see on a daily basis on how corporations want to commit themselves to a project or goal. Who's to say they won't do the same here?
[*] [b]Nonprofit Organizations[/b] - On that same note, there's more than likely going to be a lot of organizations set upon providing relief as best as they can to a world scarred by alien visitation and its deadly aftereffects. Given how they tend to act as a "middle barrier" between powerful individuals and those most afflicted by The Visitation, there could be a lot of intrigue in regards to who gets what first...and how.
[*] [b]Political Organizations[/b] - Not all political movements gain power in office, but that doesn't seem to deter any of them from trying. In the wake of the newfound chaos of the New World, there's bound to be at least a few movements worldwide looking to take advantage of the tumult...
[*] [b]Religious Institutions[/b] - Think of how, say, the Catholic Church or the International Buddhist Progress Society might function in the face of this. Wouldn't it be interesting in the Pope or the Dali Lama had to have their entire belief systems re-examined in the face of this overwhelming new evidence? How would this affect their teachings? Their interpretations? Their own personal beliefs? How they collect donations and how they continue to justify their own theology?
[*] [b]Criminal Syndicates[/b] - If it's a new avenue of business, you can be damned sure that organized crime is going to be crawling all up and down over it making sure they figure out how to get their cut out of it before anyone else does. Think of all the ways that Cosa Nostra and The Cartels could try and make good money off of selling artifacts to the highest bidder...or even keep them for themselves! 
[/list]

I hope these give you some ideas, at the very least. I didn't want NEO to be an RP where it was all a bunch of same-faced nations all trying to muscle over one another for something they couldn't even explain themselves.

Oh, and thanks for the recommendation. I'll be sure to look into it!
