no pc games have special controllers?

[nO}{8]

For the ps2 you can have a chainsaw controller, for the gamecube you have bongos, for the deamcast you have a fishing rod etc...why is there NOT ONE SINGLE pc game that has ever been released that requires a special controller? I dont mean flight sim games and flight sticks, but a game specifically designed to have a unique controller bought with it to provide a unique gameplay experience?

WHY??

But, if the game only worked with that controller then it wouldnt have piracy issues. The controller dosent have to be kiddy, use your imgaination...what would a WOW controller look like or even a silent hunter one!
