Seriously, if you have windows, and a wired xbox 360 controller, just plug it in to one of your USB ports and windows will automatically install the driver for you to use. So not only do I get to play Skyrim in such amazing Graphics with future mods updates etc, I also get the console feel with the use of a controller. As far as PS3 controllers go, I'm not sure if they are wired or can be. Or if they work in windows. But it wouldn't be bad either if your a PS controller fan.
Also, if you DON'T have a wired xbox 360 controller I suggest 2 options:
A) Go to your local gaming retail store and see if they have any used wired controllers (which will be cheaper then a new one)
or

Buy a Reciever for xbox wireless controls. Click on this http://www.amazon.com/Xbox-Wireless-Gaming-Receiver-Windows-Pc/dp/B000HZFCT2 . It's to Amazon. It's only 17 USD too

! Not bad I'd Say.
But yes, HAving the best of both worlds for me, puts this game at the top for me. Favorite game this year for me.
