I've been hearing nothing but stories about i. people getting sick and ii. the rift "completely fooling" people's senses. I had the opportunity to try the dev kit out over the holidays and I was really excited, but after trying a whole bunch of games I was actually kind of disappointed. I understand that it's dev hardware, and it DOES have a ton of potential, but I didn't even have the slightest hint of motion sickness. Maybe that's just my brain. But I also didn't feel like my senses were being fooled. Yes, I could look around and things were 3d-ish, but I really didn't find it immersive. Anyhow, I could see a high res display making a big difference in that department.

I found it really immersive when I wore it while standing up, but when I sat down to actually play the game it got a bit more "I am wearing a very cool headset".
