^that's fair, but it depends who you talk to. I used to play Guild Wars (I stopped because of exams, boredom, and my computer's limited resources) and thought it was excellent, but another fellow I was acquainted with said it was WoW Lite (which is pretty accurate by all accounts).
I've never played WoW myself - I may buy it one day and join a private server ($30 a month when I can play GW for free? No thanks, I'll either take my business elsewhere or exercise the right to private use I attained when I purchased the software) - but watching other people play it and talking to people's experiences with it, it's fine.
The subject matter is pure fantasy - about as evil as reading Lord of the Rings - and in regards to how one might react to it by spending more time playing it than they possibly should, that's simply a matter of self-control which that same person would probably be afflicted by watching the telly, reading books or playing golf. WoW isn't a special case: anything can be addictive if one has a passion for it.
