4. (economic meltdown): Yes, but you're RP'ing the nations involved in this meltdown.

I suppose it all depends on your definition of what an NRP is. If you're strict about it, then, no, a lot of these aren't NRP's. On the other hand, according to the tag's definition (from when you make a new RP), "Players control nations, tribes, factions...". While extending it to, say, TV networks is a bit of a stretch, I would certainly consider spy agencies to be factions. But then, I always love to push boundaries and try crazy things to see what works.* Point being, we need people who support a strict definition of NRP's and people who support a loose definition NRP's for healthy genre growth.

It was also surprisingly difficult to avoid sci-fi ideas when compiling this list. Some of that may be due to the vagueness of what exactly sci-fi is, and my interests are definitely biased toward sci-fi. At the same time, I wonder if NRP's naturally lend themselves toward the fantastic.

[sup]*On the other hand, my love of innovation results in me overlooking simple, obvious solutions to things like player retention. There's a reason that we have tried-and-true tropes - it's because they work.[/sup]

(RE: organs)
Yes, my problem with it exactly. :(

[@Willy Vereb]
I, too, have tried it before. Mine died off because of a lack of interaction. And, you know, goals for the players to do.

[center][h3]Moar ideas![/h3]
[sup]You guys can totally add to this list, BTW[/sup]
[sup]Quite a few of these can be generalized to not-necessarily-Earth[/sup][/center]

22. Horror nations - ghosts, goblins, ghouls, and the like. Fantasy, so not sci-fi. 
23. Dystopias - something like 1984 except with less sci-fi. 
24. Shadow governments and conspiracy theories - hard to do while also remaining in the land of realism.
25. Struggle for control of Shogunate Japan
26. Corporations battling for global market share
27. (in a slight twist of #3) Everyone RP's colonial powers trying to exploit Africa or the New World.
28. Post-dissolution of a USSR-like nation, players control the leftover states
29. RP'ers play insignificant nations vying for the attentions of one of the "Great Powers", much like the game [i]Victoria II[/i]
30. The world of any fandom: Elder Scrolls, Avatar the Last Airbender, Lord of the Rings, Game of Thrones, DC comics, Things Neil Gaiman Wrote, lots and lots more.
