I was thinking about in the future, a way were your controls are done by you body and movement of your own body. Some way were what you do with your own body is reflected ingame, but you getting hit and stuff would have to make your own body move some how without hurting yourself.
Thats what I think would be really cool.
Like virtual? As if you had mechanical shit like straps on you and the computer would read the movements and do them ingame?
