Well firstly I wasn't really concerned with how much you would have paid already in absolute terms, I'm more concerned about how much you would have to pay to be able to play on Blizzard's servers forever, which I see as akin to buying any other game (i.e getting the ability to play the game the way its meant to be played whenever you want)
To put it as simply as possible I was giving you the amount of money you'd have to pay to be able to play world of warcraft for an infinite number of years, which I see as the same as actually owning the game, hence the price of the game
You don't seem to be familiar with some of the basics of financial calculation. Not everyone is thats ok.
I'll help you out.
First you need to know what are interest rates and where they come from: An interest rate comes from the market for future money, what does that mean? It means that if I were to tell you hey you can have either $90 right now or I will give you $100 in ten years, you're prolly gonna take the $90 now. This difference is the discount rate or the interest rate. Interest rates also effect capital pricings, neutral profits, are influenced by money supply factors in modern economies blah blah blah but the gist of it is that future money can be bought by a smaller amount of present money.
Now when you calculate how much present money is worth in future money you say something like $100*(1.05)^2 to get the value of $100 today, 2 years from now at a 5% rate.
To get the value of $100 in two years today you do something similar: $100*(1.05)^(-2). This is called the Net Present Value, or NPV
Now, when you want to figure out lets say the NPV of $100 paid to you each year for the next n years you are adding $100*(1.05)^(-n) + $100*(1.05)^(-(n-1)) ... + $100*(1.05)^(-1) this is called an annuity
When n = infinity this sum is called a perpetuity. And since its a limiting sum the formula is Size of payment / interest rate. In the above example it would be $100/0.05 = $2,000
Ok so all I did with the world of warcraft thing was figure out the NPV of being able to play the game on Blizzard's servers forever. I used the Australian monthly fee of $30 in perpetuity (being able to play whenever you want)
Which is ($30*12)/0.05 = $7200
I did not take into account the up front payments (which would just be tacked onto the final answer), nor considered the actual rate of interest cause 5% is a good expected value, and I did not make it into an effective monthly rate cause the effect would be minimal.
Above average trolling.
