Any Recommendations for Online Roleplaying Games for a first time user?

I play runescape. It is a medieval game with decent graphics. It is browser based so no downloading anything. It is just ran on java. You can also become a member for only 5 dollars a month. You can do quests, buy armor, fight other people, kill monsters, and has several different minigames. It is a good one to start on. Heres the link, try it out: Runescape.com
