*Crux does not collect one-game novelty controllers (such as the Tiny Bee/Onimusha Sword/Resident Evil Chainsaw), controllers that do not work (like UForce/Activator/R.O.B./Ultimate Kick Boxing/Power Glove), nor arcade sticks cause they are too plain/standard
*Reasons why I don't collect certain types of controllers are available here
*W_W is Weekend_Warrior, which is too big to fit in the table. His multiples count because they are for different systems (Playstation 1/2, XBOX1, XBOX360)
Some of his controllers were added via private messaging, which is why they aren't listed at his link
