It would be ideal if the IG world had a finite amount of resources/gold, (indexed on the total population maybe?). That way, we can avoid inflation, and also have to make some decisions on how to manage our personal/guild finances. (I've played far too many f2p browser-based mmorpgs where inflation got ridiculous after a few years, so unless quests and the meta-game are constantly updated and evolving/changing, a cap on total resources would be needed). I'm still unsure how the economy of the world will run, though that is a major concern.
In a closed economy deflation is ridiculously rampant just imagine if anyone hordes 60% of the gold every coin would be worth ridiculous amounts because none has more then 3 gold making the 60% fortune worth more then it should. While the scenario is unlikely 5-10 people having 10%-5% each is not as farfetched.
It's true that there still needs to be enough resources, though having an unlimited amount, or no way to regulate it leads to other problems. The devs can always adjust it if deflation becomes a problem (i.e. new treasures/resources/mines found), though I'd really like to see a browser-based mmorpg go away from the 'unlimited magic pot of gold' model. That is just not sustainable.
