The year is 2129.
The Human Republic has offered up a planet, Calypso Major or 8323 Pegasi IV (as it's officially known) for colonization. Nations, corporations, and individuals are free to attempt to establish their own settlements/homesteads on the planet, as long as they agree to fall under the Human Republic laws and taxes.

Ok, so if you couldn't guess from the very short intro and the tags, this is something of a mixed RP, with aspects of both nation and normal RP. The RP would mostly take place from an individual viewpoint, though decisions there will effect your nation as a whole. You create a single character, the leader of your faction on the planet, and you play as them throughout the game. During gameplay, you will engage in normal RP behavior (fighting enemies, talking with NPCs, etc) and guiding your nation/corporation as the local authority.
Challenges would include things such as establishing trade with neighboring settlements, dealing with natives, establishing a sustainable colony, and various other issues.
This is just me putting feelers out to see what kind of interest there is.
