CNet has recently published an article entitledVirtual Gaming's Elusive Exchange Rates, in which they discuss the difficulty in putting a fixed exchange rate on MMORPG coinage. They spoke with the Terra Nova guys, who everyone knows are an academy for virtual economy.They covered IGE and GameUSD.com,a non-commercial research site providing price trend graphs for currencies of most top MMORPGs(Ffxi gil, Swg creditWow gold, Lineage 2 adena, Everquest Plat, Eq2 gold,etc.). According to the graphs and talking heads, what is interesting is that , ironically, given the dollar's weakness in world markets, in almost every case the games' currencies are losing value against the greenback because of inflation.
