Aye we become more and more sedentary everyday with all the new tech that keeps coming out. One day folks will be able to play games with there minds!

I use my PSP as a controller when I play Planetside sometimes. It is excellent for controlling the vehicles in that game.

We already can control games with our minds. It's not exact and is probally expensive but people can already do it. It takes alot of trainig tho.

In the meanwhile you can use this:

WASD+mouse all the way, its precision in FPS is the only way to go. I even remember reading a story about a guy in a Halo 2 tournament complaning about some people having a keyboard/mouse set up. (this is Xbox Halo 2, before the computer version.)

Although, certain games NEED a joystick, otherwise they are insanely hard/unfun. And that is flight simulation. Descent FTW, had a joystick that worked 25% of the time and I still did better than with my WASD+mouse controls. Otherwise, is there any reason for a joystick?

Trackball, heh. Used one a few years ago at a friends house. Is your precise? I don't think his was all that good, but I wouldn't think to leave my WASD+mouse set up for a trackball.

Well I also use a wheel for driving games heh. The novint falcon looks cool but no game support. They do have a mode for HL2 and HL2 Ep1 but that's not enough for me to buy it. and I want to try it first.
