There is a game that was doing BETA testing from july-the end of august that wsa incredably fun to play known as dofus. originally on a french server, i guess they were making an english version and working out the bugs. Dofus is more entertaining than RS or MS IMO because of the ways the battles are set up, how much control you have over your char, what kinds of spells there are, etc. the battles are turn-based using AP's and MP's to move and attack, and up to 8 friends can help you battle. Unfortunately, the BETA test is over, and it now costs like 6.70/mo.
its still worth looking at though at

The name of this game sounds pretty weird I say...and obviously if you add another "o" to it then it's doofus. Well if I have to pay for it then I'm not playing it obviously.

I don't hold it against you, and $6.70 is a lot of money...
