More physical stimuli would yet deepen the effect of game worlds. Would be nice if you could stop just to smell flowers, or cowdung if it tickles your fancy. (only game to ever try adding smells to the experience was Leisure Suit Larry 7, as far as I know, but the system was quite quirky) Or if you could feel the breeze of the evening wind in your hair while your character sits down atop a cliff to admire a glorious sunset.
Someone could create some sort of cabinet where you could play the games. Fans would provide wind and a thermostat would be used to alter temperatures, in FFVII for example, the air temperature would change from the agonizing heat of the sandy badlands to the chilly breeze in the northern continent. Smells could also be added to the experience, with tiny capsules containing the appropriate odor that are shipped with the game. And in this cabin 3D sound would be easy to implement with multiple speakers, to the sides, above and below.
All we need is to get a physical touch of the game world, so we wouldn\'t have to run around using funny pads. If you could really touch a flower covered in morning dew, feel a drop forming on your finger, pressing it to your cheek sighing while looking at the distant horizon, take your first step and see the grass beneath your feet crush under your weight. You watch to the skies as a flock of tiny birds are flying in a neat formation, which is scattered as a predator quickly swoops down at them. A real, another world to see and experience.
