It certainly is when your neighbor is a professional lawn care manager.
Edit: To the person above me, I agree. I have always preferred subscription based games. In any F2P game I have always chosen to subscribe rather than "pay as I go" because it is less hassle. Not to mention that most subscription based games have seemed to be of a higher quality in my eyes.
Final Fantasy XIV: A Realm Reborn is being released this month and I have my copy pre-ordered. Square-Enix is keeping this game subscription based and have stated, and I'm paraphrasing, that they would pull the plug on the game before seeing it go to a F2P model. I think there is definitely some merit left in subscription based MMO games and I believe that FFXIV will show that.
It will deliver a quality game that people want to pay for, or it will die trying.
