Their solution to credit-farming is quite ingenious IMHO. They need to fund the real-life servers and they know people will buy in-game cash no matter what, so they cut out the farmers and sell in-game cash themselves. That lets them manage the sales process (so e.g. people don't get spammed by gold-farmers), and forces them to structure the game so buying credits doesn't let you pay to win.
Its far from an ingenious solution at all and its one of those points we have yet to see any detail about. There is one way you can stop 'gold-farmers' in their tracks.. its like this: you dont allow money trades between players. Therefore, any form of allowing the buying of currency is a means to generate revenue for the company. If running a few servers is going to cost the earth then okay, lets see the detail, otherwise its just an excuse to create a wow style cash cow. Valve runs heaps of online games and I've never had to spend a penny outside of buying the game.
Unfortunately there is some practicality involved with online games. If it turns out revenue is required to pay for the cost of servers etc, I am happy to hear the argument and be presented with facts to support it.
There are a few issues that get me boiled up and this is one of them.
Ugh, I hate talking about wow - but I played it for a long time before it turned into eaze mode:
My point is that in the end everyone and his dog seemed to be buying gold. Several of my friends did on a regular basis. Just on a matter of principle I never did - the idea of doing so represented completely debasing the entire game.
So what was the result of the silent free for all and my living on principle?
Anything on the AH that was worth anything (i.e. purple BoEs) was immediately inflated to a price I couldn't afford - and I played the game A LOT. All my friends who did buy gold had no problem in kitting their character out, even alts, with stuff I had to work for but could barely afford, if at all.
That was just deeply unfair, in the end I stopped playing. I am still waiting to understand how being able to buy currency is not going to result in a system of unfairness whether it is bought from Frontier or not.
