Ive had the dk2 since it was released and my favorite games to test out with it has always been Elite: Dangerous & Ark survival evolved. Its really the sense of scale that makes VR cool and those two games really shows it off.(T-rex in your face is pretty darn cool!!!!)
Calyn: Did you try any VR before you got your vive? Ive been trying to find out how much of a difference the visual quality is between the final versions & my dk2 but very few talk properly about it(atleast that I have found)
