I'm curious about how you would stimulate the feelings in the game, lets say you get hit with a pebble in the game(haha) would there be chemicals released into the brain to stimulate the feeling? that's pretty sketchy so no to that. Hmm what about electrical waves? If you send electrical impulses that would activate parts of the brain responsible for feeling and let the eyes take care of the rest?(you see yourself get hit by the pebble and the NerveGear (placeholdername) sends an impulse to the proper part of the brain and the image you saw would trick your brain?
