mmm... i dont think so. i think W.Gibson's cyberspace (my concept of cyberspace) must have influence on the "atoms world"
something like "i enter cyberspace, access my house through the interface and start the heating, turn on the lights and program the "TV Signal Recording Gadget" "
so everquest isnt cyberspace, even if it has an "avatar", day/night, areas to explore, things/people to interact with, money/economy and so on.
