GC is a good concept, if you can buy everything in game money then you can buy population by having good corporations? GC is super space age awesome money that has a price. If I try to give cuba a billion dollars to give me their country it would never happen, but if I try siper space age awesome money maybe they will. The only problem is the balancing issue if its impossible to get then whats the point? If people are willing to sell it or buy it but its intrisic value is much higher then the maximum sales price then there is no selling it buying it.
