That's the sort of thing that is interesting to people like Eyjolfur Gudmundsson and Yanis Varoufakis, economists who have been hired by game companies CCP Games and Valve, respectively, to manage their games' economic models. They've since discovered that these games serve as the ultimate financial experiment, allowing experts to observe how markets fluctuate, survive, and thrive in circumstances that can't be duplicated in the real world.
After all, you can't just simulate economic theory on a computer and see how it goes -- real economies are made up of human beings, and it's pretty much impossible for a computer model to guess what they're going to do. And you can't just try shit in the real world to see what happens -- not even tiny little booger countries like Andorra would be cool about becoming an economical petri dish that may or not result in total depression. But in a gaming world, you have millions of players dealing with virtual currency and goods -- things that are totally real (to them) and cause them to make decisions accordingly. Players work for in-game "gold" (by killing monsters or crafting items), and, therefore, that gold represents their labor ... just like real money
Given, the cash drawer has to be super freakin' sturdy.
