Yes you can. I suggest that you buy a wired controller, a wireless controller you need to buy a receiver which costs about $20 dollars and I had a hard time finding one, so you can just save money by buying a wired one with cost about $25, after you get a controller you need to download a driver here is the link http://www.microsoft.com/hardware/en-us/d/xbox-360-controller-for-windows and some games don't allow you to customize the button layout so download xpadder the link is http://www.softpedia.com/get/System/System-Miscellaneous/Xpadder.shtml xpadder is awesome.
plug into usb port
No that's y there called x box 360 games retard!!!!!
yes you can, most of them, let's say that you can play like the 90% of all the released games of the x-box on the 360
No sorry the X Box 360 discs are far too advanced for the original X Box, they just don't communicate, but, vice versa you can play original X Box games on the X Box 360.
No you can not
yes u can
Hardly any games let you use a controller that are made for the computer, whether or not you can play against people playing the 360. If there's no option in the settings of the game to use a controller on the computer game, then you can't.
only certain x-box games work on the x-box 360 for others you must download harware
No. Several games for the xbox 360 are custom tailored for that system's software and hardware, and simply upgrading your xbox will not allow it to play xbox 360 games.
No
No.
Well for some games yes but you would have to use the balance board which is technically not a controller.
