I will say the same thing about this as I have posted on FB.
60 bucks is a lot of money for a bloody microtransaction. These sums cannot be even considered "micro transactions". Not at this amount.
If the devs used their brains and would decrease the prices people would be more inclined to buy something.
Example: Paying 20 bucks 3x times a month, does not feel that bad as paying 60 bucks straight up front. Its the same in the end but feels different in person.
If they reduced the prices they put in the game (mainly the cost of nutaku gold) people with lower budget might be able to afford them, and they would actually make more money since more people would like to buy something, rather than the miniscule amount of wealthy players who dont care about throwing around hundred of $$ each month.
Many devps. know this and thats why games like Dota2, League of Legends, etc earn shit tons of money, Because the Micro transaction is small enough to feel insignificant - but once you buy multiple of them you still spend a lot of money at the end of the month. Korean MMORPGS do it this way and works, heck even WOW is doing Micro transactions these days, seeing it as a working business model.
