its not so much the addiction as the time consumption. if you're the casual player and enjoy doing your thing, then you should have no problems. if you wanna see everything the game has to offer and work on getting the best possible things for you character, then it becomes the worlds largest timesink. be it that you wanna do the pve side and raid in the latest and greatest instances or you wanna do the pvp side and duke it out with the best in the arenas. you have to sink a ton of time into both to be any good at either, but then again, that can be said for a lot of things. but, with my past experience with gaming, since you have to rely on other people and their scheduling conflicts, wow definitely takes the cake from making life more inconvinent.
