I believe that VR technology is the future of the gaming industry. In a few years, VR will replace conventional gaming consoles.
Looking at what level of technology over the years will be achieved. It's more convenient for me to lie on the couch and press the joystick than jump and run around the room.
You are making a good point here, but I think their setup is quite coherent with those parks. People who go to those parks are going there exactly because they don't want to lie on their couch. It can be quite a fun event to play in such a park with a huge group of friends I can imagine.
