If you make a game and then spend more time worrying about its economy than its gameplay, you’ve failed at making a game.
Now I don’t at all feel that ANet has failed in making a game but I often feel they’re focused too much on the economy. I’ve never worried about making money in an MMO so much before. I suppose it’s not surprising when you can pay real money to buy a currency you can then exchange into in-game gold. It’s probably in the company’s best interest to make money making difficult and allow the more rare or desirable skins cost extraordinary sums of money.
