I want to sit down and enjoy my game. VR is never going to take off if you have to stand, duck and move around so much to play.
I think this is why Oculus didn't focus on roomscale at first. I get so annoyed when I can't pick something up from the floor because my camera is obstructed.
Currently I have the front facing setup and I put my sensors closer to the edge of the desk while one sensor is point slightly downwards to get to the floor and the other is pointing slightly up to get my hands in the air at full reach, works really well! 🙂
I sort of agree that room-scale isn't the be-all and end-all. A good seated experience (e.g. Eve, I Expect You To Die, Chronos etc) is every good as any standing experience.
