I have one word for you. Nanotechnology. Currently they have nanotech that can find a point in the human body. sent these to the cortex of the brain that controls movement and receives signals for your senses from this point the nanotech blocks these signals receiving the signals instead. these signals are then transported to a band that sits on your head there is a visor the covers your entire face. this band wirlessly transmits these signals to a computer and the computer sends the signals back to the band which then tells your digital character to wave its hand, run, draw weapon, open a door, take an item, etc. these nanites are wirelessly charged and wirelessly turned on and off. to turn on simply turn on the computer tower witch will send you into a white room with a drop down menu with a games list, a social chat room, a store(for downloading new game content, and updates to the computer the headset, games, and the nanites), and a power off button to power off the entire system.not only would this advancement in technology create a better way to game but it would creat advancements to military, education, and medical fields all together.
