I find this very interesting and would like to join the discussion. I would like to bring up the sub topic on how to actually create the games themselves. In the science fiction anime, Sword Art Online, they create the VR world using polygons. Polygons, in other words, a collection of coordinates and surfaces, the digital data. Polygons are used in computer graphics to compose images that are 3-D in appearance. Could this method of rendering be probable for the creation of games such as Sword Art Online and other VRMMORPG
