The Controller - Pong to PC. Wii takes step back, Dual Shock holds steady.

I think this kind of missed the point of control evolution. It's not the buttons, it's not the control sticks, it's the convenience factor.

PONG - Simple analog wheel. Linear precision control only. Pretty easy to use.

Atari - Various input methods, most notable being joystick + button. Still linear precision control only, and very stiff.

NES - D-pad input. Linear precision control, easy to use.

SNES - See: NES.

N64 - Analog input. Non-linear precision control, a bit too loose.

PS2 - See N64, but too stiff instead.

Wii - Analog, camera, and motion input. Non-linear precision control, but imprecise for motion input (MotionPlus should help with this).

PS3 & 360 - See PS2.

PC - Key-based input. Linear input only.

PC has keys and a mouse, so there's two axes of movement there...

And you cannot ignore PC dual analog controllers that a majority of games support.
