We have just posted our review of the Microsoft Xbox Game Controller. Here is an excerpt:

A great feature on the Xbox controller is how if you have someone walk past the Xbox console and pull the game controllers cord by accident, you would expect that the Xbox console would come crashing down with it. Well with these controllers it doesn't happen and believe me, I've already managed to test it by accident. At the bottom of the Game Controller cord is an Inline Release, this means that when you pull against the controller cord too much, the Inline Release splits from the console connection and thus this means that the console will not fall down and be damaged. Then once this has happened, all you need to do is to connect the inline release back into the Game Controller connector in the Xbox.

Some of the titles made good use of the "Rumble" feature built into the Xbox Game Controller. This is basically simple force feedback styles, similar to those seen on the PC although not quite as advanced. The best title to make good use of the Rumble style is Halo, with you being able to feel each different weapons firing style.
