Some controllers are superior to certain genre of games. FPS needs keyboard and mouse, but flight simulators demands joystick (tho I had fun playing F/A-18 with mouse, had to move it breddy carefully and stressful situations - liek getting into a fight with MIGs - could lead sudden mouse movements which resulted into losing control entirely, so keeping cool was a must). Sometimes I wonder how racing games - such as the NFS series - would run with steering wheel, I had a pal who bought one just for that.
