Such a restriction would DESTROY the gaming industry! Gamestop would all but go out of business, as I'm sure used games are a large chunk of their business. It would ABSOLUTELY DESTROY services like GameFly because if a single copy is designated to one system, you have destroyed rental services. It would also prohibit you from playing your copy of your game at a friends house. This is the absolute worst idea! I REFUSE to buy a console with such restriction. If Microsoft or Sony implement this idea - - ENJOY BANKRUPTCY!!
