If you're really, really into driving video games, you know that using a regular controller or a keyboard is for chumps. It's a driving game, so clearly you need a steering wheel. But while most people are satisfied with just a wheel, some people need more. A lot more.
Enter the VirtualGT Racing Simulator. This behemoth is designed for realism, coming loaded with a 37-inch plasma TV and a whole seat/wheel/cockpit contraption. It also has tons of high-fidelity speakers to make you feel like you're in a real car. Of course, for the $20,000 price you could be in a real car, but I guess some people have different priorities than others.
