1). Yes, Space Pirate Trainer is currently my #1 VR title by a wide margin. Out of Ammo is also pretty fun, but something like an order of magnitude less fun than SPT. 2). Few in the consumer space, most of them are tech demos with little real utility. Tilt Brush and Google Earth are among the most compelling non-game offerings. 3). I've made some half hearted attempts at REPL/console type stuff in VR. It's barely useable, the angular resolution is still prohibitively small. I use 4 physical monitors normally, and while I like the idea of replacing them with a VR headset that future is still quite far away. 4). I've also made some half hearted attempts at this, and others have tried as well, but this was in the era of the DK1 and I didn't achieve anything meaningful. I'm definitely going to give it another go with the Vive at some point. The LEAP motion however integrates very well with VR (either headset) and I'd recommend experimenting with it. I've made some pretty compelling minority-report style tech demos that feel pretty natural to use. Granted I'm aware of the LEAP's tracking limitations and stay within the space of gestures/hand poses it recognizes without problems. When I demo the tech to other people they often have MUCH more trouble than I do. Mostly because of occlusion problems. The LEAP is basically just 2 cameras without much stereo separation so one hand occluding the other, or the back of the hand occluding the fingers etc is something you've got to be cognizant of when using it.
