I agree that it would be nice to be more involved in games since the ability to put a player in a virtual reality is much easier than it once was. However, the only problem I find when speaking on this topic is movement. Aiming and looking is all fine and well... but walking, running and strafing would all be very difficult without a pair of sticks.
Your ideas aren't bad it would just remove a person from the Virtual Reality you are trying to create. Why put a helmet and a gun on someone and then tell them they have to move around using a stick... doesn't make sense.
