What? It's true. If I enjoy the game enough to pay 15$ a month for it then it's completely worth it and would not be expensive in my eyes. For example, I played the WoW trial and while I enjoyed it, I didn't enjoy it enough to pay the monthly fee. So if I were to play and pay anyway and after a couple monthsI felt the same as when I played the trial I'd say, "Damn, that was expensive/a waste of money." But let's say that I love the trial, bought the game, and played it for a year. After that year if I were to look back and think about the enjoyment I got from the game I'd think, "For the experience and entertainment I had the monthly fee was worth it."
The problem with your view is that you're not looking at how much money you spend on a game all together, you're only looking at how much money you spend at a single given moment. You're saying "15 bucks - that's not a lot!", while in actuality 15$ per month
is a lot if you're planning on playing the game in question for a while longer. For example, I bought Morrowind for... I can't recall, but it was at least a
normal game price for a change, and have happily played it for the last 8 years. Of course, I haven't played it every single day, but since we're counting months, on most months I've played it for
at least a week (although not 24/7), so my estimation is that the months in which I have played Morrowind amount to approx. 5 years, which is 60 months. If I were to play World of Warcraft like that, for those 60 months I would've had to pay
900 [censored]in' dollars!!! And enough with the [censored], no matter how much you "love" a game, you simply wouldn't pay that much for a single game, especially not given the amount of content and game-play in a MMO like WoW.
