This question already has an answer here:
I recently bought an "Xbox 360 Wireless Controller for Windows". It came with a little USB dongle for my computer to pick up the wireless signal and some driver software. It works like a charm.
I plan to have some multiplayer games on my computer, so I want to hook up three more wireless controllers. Here's my question: should I buy more "Wireless Controllers for Windows", which are a little more expensive than just regular Xbox 360 Wireless Controllers. or now that I have the driver software and the USB dongle, can I just buy regular Xbox 360 Wireless Controllers?
Is there any actual difference in the controller hardware itself?
