Group 8 - Virtual Reality

I know virtual reality is used for training purposes in the military, but I'm familiar with virtual realities through sci-fi books such as Ender's Game and Snow Crash as well as films like The Matrix and Tron.  As a gamer, I'm not really sure what separates virtual reality from video games.  I know the feeling of being immersed in a video game, and it seems to me that it would be difficult to get immersed in virtual reality while wearing the clunky goggles and gloves.

Questions on "A BRIEF HISTORY OF VIRTUAL REALITY AND ITS SOCIAL APPLICATIONS" (Samuel Ebersole)

1.  Are books, films, and video games all different mediums of virtual reality?  Which mediums, if any, should be excluded?

2.  What is "virtual rape"?  How did it impact the virtual community of LambdaMOO?

3.  Should a person feel guilty for any actions taken while in virtual reality?
