I hardly see the point, I spent about £250 (est. 366$) on my computer's GPU, CPU and RAM, all the hardware is outdated by about 3-5 years, though it still runs Crysis on highest with no visible lag outside of the most hectic areas. Maybe I'm missing something, but last time I checked that had the highest requirements.

I don't see the problem people have with joysticks, they are more or less like mice only they flick back to center after movement.
