Are there any good RPG games that don't require downloading besides games related to Adventure Quest?

For years I have been faithful to my RPG game, but now I’m in need of a new one. I prefer games like Runescape. I have already tried Adventure Quest, Dragon Fable, and the like, and they all left me unsatisfied (I’m kind of extremely picky.). Do you know any games unrelated to Adventure Quest that don’t need downloading?
