I have played both wow and runescape a lot over the years. I hope this hasn't been said before in this thread, but atm i'm kinda too lazy to read everything, anyway, here goes: If you're a hardcore player in WoW, the content gets old and boring so fast. You get a major content patch in about every 6 months, few months here-there, where as in Runescape the updates are constant and happen more often. For someone who said that WoW has weekly updates, you're wrong. WoW has weekly server maintenance and sometimes they toss in some bug fixes and other stuff like that to the game during them WoW has turned into a game where you basically just log in and get the best gear, a casual, care-bear game. But in runescape things actually take some effort and there is a death penalty, which is a very important aspect in mmos imo. //edit: also, the poster above me summed some things up really nicely.
