One of the more contentious rumors surrounding next-gen consoles has been potential changes to DRM and while Microsoft hasn't answered all our questions when it comes to the Xbox One, it took a few head on. The official FAQ starts off with the "always-on" DRM issue and also addresses used games, indicating that the box is designed "so you can play games and watch Blu-ray movies and live TV if you lose your connection," and that it does not have to
always be connected. That said, it still "requires" a connection to the internet, promising cloud-based benefits for gameplay and more. Other questions answer things like whether the new console will require more power (no) and will our Xbox Live Gold subscriptions still work with the new and old hardware (yes).
When it comes to used games, the FAQ's response is also promising, stating "We are designing Xbox One to enable customers to trade in and resell games." We can still find enough wiggle room in those responses to remain curious, but it appears we should be able to avoid a SimCity-style meltdown (with our new games, since the old ones won't work.)
