slightly OT...
I've been playing WoW on and off for some three years now. Never once would I say I've been addicted. I play when I want to, but I do other things (like blog, knit, bake bread, go to work when I can, play with my cats, pay my bills, etc). I use it for escapism, yes; it's fun to get lost in something else for awhile and forget your problems. But I also play it because it's a game I enjoy. I play other games, too (Harvest Moon, anyone?). I also use things like books as escapism. It's just an extreme way of 'getting lost' in a story. I do the same thing when I write, larp, and tabletop roleplay.
It's never stopped me from dealing with my problems, but sometimes it has given me a breather, so I can get away from them long enough to think straight. Can't any activity be like that?
Point being; Yes. It's entertaining and I love it when people take my male characters at face value, as guys, without me worrying about my voice or hips or soft, silky skin. It doesn't, however, offer anything even close to a replacement for dressing and presenting in real life; even if real-life is a lot more hit-or-miss for my passing.
It doesn't have to be unhealthy. Anything can be addicting, escapism-enabling or otherwise.
