I think it’s in the book “Games of Empire” where the argument is made that the worlds in fantasy games are usually just recreations of our modern capitalist world, aforementioned financial shenanigans very much included. These games often have the aesthetics of a kind of mediaeval feudalism, but in-game economies feature very modern things like decimalised currency, auction houses, arbitrage, consumerist alienation, instant payments, and so on, all of which would be very out of place in a feudal world. Fantasy RPGs show us worlds that appear radically different from our own at first glance, but upon deeper examination they are another example of the social imaginary restrained by capitalist realism.
