Seriously, this is something you need to see rather than read about (see video below). Personally, I worry about the immersive nature of the technology. I know, I know, the point IS to be immersive. However, I think there is also a point that it becomes dangerous. After playing 6 hours of Dragon's Dogma, I remember feeling so disoriented about what was real (for that some reason, that game is so jerky or grainy that it makes me sick after playing for too long). I went on a run, and I had a hard time adjusting back to reality. Maybe it's just me, but there is going to be a line to cross at some point where something is TOO immersive. However, regardless of my feelings, Microsoft has come up with something interesting, and I appreciate that!
