let's try a thing. you can do anything that isn't completely overpowered, creating money or removing the concept of money. every new type of object that is created must have a worth.
Also, I will constantly adjust the money pool to compensate for the amount of stuff in the game universe. Three currencies will coexist, and you may join one currency or another as you wish. I am the government, and I will have programs that kick in if you are too poor or too rich. These will get tougher on the rich as the game progresses.
GO.
