The real threat, though, comes from Metro - now renamed Modern UI - which is so important that its dedicated store is simply called "Store".Games in here are firmly the likes of Fruit Ninja and Doodle God, rather than Crysis 2, but what matters is that it's a slice of the PC gaming industry that Microsoft gets to outright control. Nobody else can sell Modern UI apps, and it gets to both take a cut and dictate exactly how they work. The rules are here, covering everything from the type of ad these apps can show, to how fast they have to load, to prohibiting any touch controls that contradict Windows 8. The games available on the store are no big threat to anyone but the casual gaming portals right now. If successful though, it's easy to see this level of control stretching - and love or hate Windows 8, there's no denying that a big chunk of it is about turning at least the default PC ecosystem into a more Microsoft-friendly one.
