Legend of the Green Dragon
http://lotgd.net/referral.php?r=KaliI used to play this a lot when I was fairly active here on FH (yes, years back). I looked for it and it was still active, so I am playing it again. Basically it is a text based rpg wherein the main goal is to kill the green dragon (something you can do once you reach a certain level).
