How many times have you been playing a game that required some depth perception. Flight Simulators and Racing Sims come into my mind first, then of course some of the Action/Adventure games that require you to jump (I truly hate them!) and grab.
In today’s gaming market the big hype is about who has the fastest video card, who has the most fill rates, or what the frame rates are a 1,000,000 X 1,000,000, but what does that mean if you don’t have anything to display it on? A typical monitor still displays everything in 2D no matter what, sure the characters and environments are rendered in 3D, but everything is still flat.
