Luna online is a MMORPG where Elfs and Humans must bond together to fight the evil that invades their land. There is a "Match making system" which will find someone else in the server for you to match your character builds, such as if your a mage with low armor. It will find a good tanker to be your "match partner", once found your perfect match you will get some aditional powers...if your rate other users "good" and have good personality with them(like Sims) you can match up with them again or even bond into the "family system".
