What I'm getting as is we're already trying to fake ourselves into what we hope gaming will be one day. When video games finally start to shape and alter our reality. It might bleed through at first as useful devices that alter our reality for actually beneficial things. There are some such devices already being tested, such as finding the price of an item in store or identifying a building or structure, doing research on an object automatically through the net just by looking at it. Then it'll shift as we find ways to use it for entertainment. Eventually it'll come to a point in which the lines between fantasy and reality don't actually exist anymore as they'll be one and the same. This is a good thing for the most part I think assuming it doesn't end up killing us as we inevitably die in the fantasy.
Just imagine what games will look like in a century, going from virtual reality to altered reality and beyond. What kind of game could you make and play if you were completely unrestricted?
also, perfect timing for a joke
