You're acting like the whole point of Runescape is quests. This is completely untrue. I for one, hate quests, but I still love Runescape. I love to skill, monster hunt, play mini games, hang with friends, and do PvP. I don't know how you can say that the goal of Runescape is to complete all the quests. You can do whatever you want, and make your own goals. If you simply "won" or "completed" the game once you finished all the quests, I think a lot of people would be rather disappointed. You choose your own goals in Runescape, whether it be getting 99 in a skill, getting a certain amount of money, or whatever.
