I always liked/paid attention to this aspect of MMO's. I really enjoyed playing the AH in WoW, it was an important part of that game to me. So now Guild Wars 2 and it's economy. Right now the market is saturated after problems with the Trading Post. Obviously their plan to control the economy has gone wrong, which created even more problems due to high prices for in-game items. Purchasing power is high, but it's limited since they stopped their digital sales which means that the diffusion rate is also high. This of course affects their Gem Shop, but is it what they want? Scarce possibilities to make gold thus a higher need in gem to gold conversion?
What do you think they will do? What kind of consequences can we expect? What would you do yourself to shape up the economy in a healthy way?
