If you like CN type politics however, a lot more interactive game, Eve online has free to play option to try the game out for as long as you like.
If you sign up through my referral, and later upgrade to free account, *I* get, ~1 bn isk (eve money), which i'll transfer to you. The worth of ~1bn$ is like ~$20, if you were to purchase it later. ~1bn isk takes a couple+ months to earn on your own, but by using referral, you get it for free. I dont get anything out of it, as I'll pass on the money (and I dont need it).
The game has bit of a curve, but the community is very welcoming to new players and there are great alliances who focus on improving you as a new player.
So if you're interested, let me know. Start downloading the client and pm for referral.
