This is a game similar to NationStates, but so much better. It's called CyberNations. You can start playing on CyberNations.net. Set political standpoints, trade agreements, wage wars with Tanks, cruise missiles, soldiers and even nukes. Develope your nation with infrastructure, purchasing land, technology and improvements. Send aid to nations in need with technology, money, troops, etc. It really is a great game and I'm completely addicted.

And the main difference with this game over NationStates, is that you can wage actuall wars, and people can die. It's great.

There are also many different alliances to join, and trade with other nations, collect taxes. There's just so much to do in the game, and the forums add a new dimension, as the majority of topics are all roleplayed.

Enough prattle from me, go here and enjoy: CyberNations, a million times better than NationStates.
