And my final part on 'The Immersion Arguement' is:

Virtual Reality Immersion

I'd like to point your attention to this particular bit on this page:

The term is widely used for describing immersive virtual reality, installation art and video games, but it is not clear if people are using the same word consistently. The term is also cited as a frequently-used buzzword, in which case its meaning is intentionally vague, but carries the connotation of being particularly engrossing.

The sensation of total immersion in virtual reality (VR) can be described as implied complete presence within an insinuated space of a virtual surrounding where everything within that sphere relates necessarily to the proposed "reality" of that world's cyberspace and where the immersant is seemingly altogether disconnected from exterior physical space.

Now, to be more constructive can we offer suggestions on how to improve the play-to-play immersiveness of the game instead of bickering over what one simple word means?
