Walter Kim has a website called Virtual Reverie. According to the titlebar it's about "Inquiries into the internal and external dynamics of VR", but his about page says:

Don't let the titlebar fool you: this is a website about videogames. As of this writing, analytical and critical perspectives on videogames are still relatively new, still in a tempest over what videogames truly are and what they can be. This website is founded on the belief that a certain type of videogame, from its earliest forms to present day ones, are best understood as primitive forms of virtual reality, or VR.

This sounds like an interesting point of view on interactive entertainment. I look forward to reading more.

Update: alas, Virtual Reverie is no more.
