I really am going to have to agree with Ostheim and say (hope) that the future, distant distant future, of gaming will be millions of users interacting through some sort of neural interface. Virtual Reality? Let's take it a step up and make it Simulated Reality.
Suppression? Well, you don't really want to be shot when it feels real. "Tank Jumping"? Let's see how fast you can get the hatch locking mechanism open with your sweaty, oily, bloody hands. Adjustable Sights? You squeeze that sides of that range bar and do it yourself. Vehicle Interiors? Obviously, it's simulated reality. Fear of Death? Oooh yeah. You die, you die. Use your mind to bring up the menu and create an entirely new persona.
Of course, this is probably 2050+ technology we're talking about... but I can dream.
