Then you turn around and sell the game for two-thirds the normal price to other patrons that have not yet enjoyed the title. Such has been the model for stores like GameStop. The great part about that business is a recession can sometimes help their market, as gamers look to save a few bucks any way possible. Well, today Wal-Mart launched kiosks in 77 of its stores that vend used video games. Looking like a RedBox DVD kiosk, these automated machines are full of bugs, but spell trouble for businesses like GameStop. This should also pique the interest of used-game opponents and provide a bigger target for them to go after if they get the politicians on their side."
