There's no doubt about it. Video games are one of the most expensive habits next to hardcore drug use. Not only do you have to invest in the system you prefer, but each new game will run you anywhere from $40-$70, and that's not even including special or collector's editions.
Even with all that accounted for, that's still nothing compared to the price that some of the people on this list have paid. Whether it's a child dropping all of their parents money on virtual coins to buy cows or people spending more than you will make in your life on a club that exists solely in the virtual world, these people really know how to spend money on their filthy habits.
What is the most money spent on a game? Take a look here and see how foolish some people are, that they're willing to fork over so much money for a video game.
