You can plug your XBOX 360 controller in to it. That is what I use. Both Microsoft and Logitech offer XBOX360 USB controllers for the PC. The corded one even has an adaptor that you can plug in to an actual XBOX 360.
I got the PC version Madden 2007 a few months ago from TARGET for only $9.99. I got to tell you I was really impressed. The graphics on it were better than on my old XBOX. Madden '07 plays flat out awesome with the XBOX 360 controller plugged in to my PC.
I really don't see the need to pay extra $$ for an XBOX 360 or a PS3. To me it is an unnecessary expense.
The XBOX 360 & PS3 both have CPUs, GPUs, Ram, Sound cards and everything else that a PC has. If you are reading this post right now then it is very obvious you already have a PC. If you already have a pc why buy a console when you don't have too? I don't think console gaming is really better than a PC.
For example: My Sapphire x1950GT video card is derived from the same R500 chip as the XBOX360. And it only cost me $139 at the time. That is much cheaper than spending $399 for an XBOX 360 console. And the thing is that once you buy a console the graphics are not going to or improve or get any better until another console comes out about 5-7 years later. Where as with a PC stronger video cards come out annually if not bi-annually in some cases. You can upgrade your graphics at any time. And you can play pretty much the same games on the PC as you can the consoles. RTS games are AWESOME on the PC which is really something you can't play easily on a console.
I am sticking with the PC. I LOVE PC Gaming. Madden 07 is a lot of fun on the PC.
I was just wondering if anyone had 08 yet on the PC and how it was.
