Nice idea but can't see it attracting many players, everyone would be doing the same thing unless something else was added it would become very dull after a while.
Maybe better for an offline single player game with maybe mp options to compete onli…
Yeah i read about this game, one of the highest prices ever paid for an ingame "virtual" item/land, is insane how far people are willing to go.
But your right this person should make his money back and i bet he/she knew this when buying, after all …
