Having used Microsoft HoloLens for more than a month. Microsoft is doing a disservice to a great product by dropping the ball on HoloLens compatible games & software. It has potential to greatly transform gaming. It ought to start dropping the price and releasing more titles.
I have also used HoloLens, and Microsoft is not targeting gamers right now. They want engineers etc, corporations and universities with deep pockets. IMO the FoV is too narrow for the consumer market/gamers at this time. It is perfect for what they are aiming at right now though.
Microsoft is surely targeting gamers, they showed Robo Raid during the presentation, including even an unreleased version of Minecraft. Robo Raid & Fragments are way more polished and utilize significantly more capabilities of HoloLens compared to any other app.
