DieRuhe: I wouldn't pay to level up in any game, and I wouldn't pay a monthly sub to keep playing a game. I really don't know how this ever caught on; I just don't get it. "Buy this game. And - isn't this great? - every month thereafter you get to pay us again in order to play it!"
its only 15 bucks for sub. seeing how many hours people put into the game playing wow is one of the cheapest entertainments out there.
your total cost per year is
15*12=330
game: 30 bucks (assuming an expansion every 2 years for sixty bucks)
so 360 bucks a year
seems to be a lot for a video game. even if you assume only 10 hours per week thats 520 hours in a year on average spend on the game.
cost to play for one hour is: 69 cents
...
compared to:
going to see a movie. 2 hours. min. cost is what. 5 bucks? so you pay 3.6 times more for the entertainment. add to this parking, overpriced cola and popcorn, charging extra for 3d movie...
playing wow is cheaper than going to the movies. Analyze your expenditure on entertainment. You will see that you are spending more money per hour than regular people who play wow.
MMO might not be something you like. I don't for example. I don't see appeal myself. Yet you shouldn't be surprised that people pay to play it as it really is not expensive.
