Sorry for not replying earlier. I never notice when I've got replies on HN. I guess I forgot to mention a big part of it: the original commenter said he felt like he wasted his time playing WoW. If that's how you feel looking back on the game, then that's a problem. But you're right, if someone doesn't feel like they've wasted time on games, then that's great. Most people I've known have felt like it was a waste, but I can see how some people would think differently.
