Don't know if it's been posted before (slap me if it has) but it's a neat text base war game, sort of a mix between Battlefaeries and Tradewars, and it's free. Good way to pass some time when you're bored, at work, etc.

If you want, you can also become an officer under me which gives me an additional soldier, and in turn my army will automaticly defend you if you get attacked by someone.
