Re: Game World Economy
It really depends on the campaign. Lighter, more swashbuckling games I'd use the gold piece standard. Dark Sun, one of my favorite published settings, of course used water. For more in depth games, I like the added flavor of using different currencies. Especially since you can use them as plot points, i.e. why is this supposed brigand's purse full of Darian gold talents? Regardless, I tend not to sweat the actual economics of a fantasy world. As long as there nothing glaringly weird about it, rich areas are rich and poor areas are poor because I say so.
