How many money have you spend on WOW

I have been playing World of Warcraft since the initial release date. The game cost $40 initially, plus the first expansion at $40. $15 a month for 4 years this month. 15(4*12)+40+40=800 $800 over the last 4 years, but it was entirely worth it for me. I do little else entertainment-wise, and therefore I pay for my internet, and my WoW subscription monthly for my total entertainment budget. For someone like me who is addicted, it's a great investment. You just have to think about how much time you're going to play versus the cost to determine whether it's financially efficient or not.
