I'm game for all three NRP ideas, but I like the Adruis and Final Frontier ideas the most.

I also like the idea of non-generic NRPs, with unconventional gameplay and focus beyond large nations. I like more personal-centered NRP's, where major figures greatly sway the course of nations and societies and wars. Alternatively, we could have a NRP more centered around ideologies and beliefs instead of technology and raw numbers.

Regardless of what you intend, I look forward to any of them.
