It's a question of predictive value. Economics definitely has predictive value. Eg supply and demand, the emergence of money, price elasticity etc. Economies in video games fascinate me, because it's another 'world' where you can see whether some economics principles apply or not. Eg the game Path of Exile doesn't have 'money', but various crafting materials ended up being treated as money by the players. The exchange rates between them are set by supply and demand as well.
