The field of view is, to me, very wide. I'm not trying to show it to an audience and it is more than enough to immerse me. It is also important to note that the field of view comes with parallax: you can really see around corners. It is not just a wide field of view on the same stereo pair.
What happens if you move your head up and down relative to it (vertical angles), does the object not get vertical parallax?
A sni[ing game would be fun - with a foxhole view where you can move behind occlusions and shoot at small things far in the distance...
The feel is that of a periscope's view though...
