Not all Vive games have to support room-scale games, it works for sitting down/cockpit games just as well. Beyond that, I really do think that the front camera (supporting AR to a degree, and being able to grab a drink or use a keyboard) and bluetooth/phone integration (immersion, collaboration) are the biggest technological advantages the Vive has. Recently game devs have been gushing over it, but when it comes to gamers typically the price really is the deciding factor regarding hardware adoption.
