YouTube user Radical Dreamer has stumbled upon an exploit in Gran Turismo 6 that can generate 20 million credits in a matter of minutes. Sounds too good to be true, right? I had Dale test out the glitch and he ran into some major issues with freezing that required a hard reboot. Basically, if you choose to do this (instructions below), make sure you aren't in the car you're about to sell. Otherwise, GT6 will freeze every time you enter your garage.
Should you inadvertently get into the same situation as Dale, you'll need to repatch the game and change cars to get GT6 back to a functional state.
