People are saying that his devotion to WoW is a bad thing, but why isn't devotion to a partner just as bad a thing? Do they not take up just as much time? Do they not cost at least as much, if not more, money to maintain? When you fool around in WoW, you use up some time, maybe get some epics out of it. When you fool around with a girl, you get emotional dependency, sometimes financial dependency, and sometimes a baby. Children are a lasting consequence of relationships.
Why is it presumed this is better than a temporary addiction to WoW, which will end when the servers go down (which would be a lot sooner than 18 years - the time to a child being an adult)? A lot of you are right - he has blown a chance to get married to a girl for a lifetime. He has decided not to devote the rest of his life to one thing (i.e. one relationship with one girl) and instead has chosen to devote his life right now to one thing, and has left his future open to other possibilities, which will at that time appeal more than WoW does at the present.
Basically, why is a lifetime commitment to a real-life partner preferable on the grounds that it is a better choice in terms of not being shackled to something?
