Earlier in the week, Russian publisher Nomoc, together with developer Qplaze, announced their MMOG Age of Heroes Online had reached 111,000 subscribers in Russia and Europe.

The game, which is cross-platform and can be played either on mobile and PC, relies on micro-payments for its business model, so with an iPhone port planned, we sent some questions over to Qplaze's Ivan Konstantinov to find out more about how the system worked.

Pocket Gamer: How do you make money in Age of Heroes Online?

Ivan Konstantinov: There's an in-game currency called Divine Grace that can be bought for real money. $1 is the equivalent of 100 DGs. You can do this via SMS, WebMoney or credit card.

This is used to buy special in-game abilities, which speed up the playing process. There are more than 35 abilities in the game, and the cost of most of them is less than $1. (You can see a full list of the available services here.)

What's the cost of the most expensive services offered?

That's would be the Player versus Player experience multipliers, which are used for rank building. These are $24 a year.

Is there also a subscription fee?

You must use the micro-transaction to pay the subscriber's fee which required to continue playing after the starting three-week trial expires.

Yes, for iPhone, it will handled with its in-app micro-transaction system.
