Played WoW a bit back in 2007. Got to level 70 on my Undead Rogue and after that it just became boring. A lot of people at the max WoW level say "that's when the game begins", but that's extremely superficial. It becomes exactly like the endgame in Diablo II where you just do X instance over and over again (Baal runs anyone?) to gain better gear so that you can gain better gear. And the PvP is fun for a little while, but quickly loses purpose (I'd rather play MW2 for the same kind of "feeling"). So really, WoW was only fun for me in the beginning where I was a newb and grasping all the new concepts and interesting environments, but after that it just became boring and addicting at the same time. I prefer RS way more since to me it's not as addicting, but when it becomes addicting it's actually quite fun to me. I also quite like just the general feeling of the game, which has never really disappeared for me (like it did with WoW). But WoW vs. RS is really just a matter of preference and mind set I'd say.
