A free mod for Dragon Age, by FREAKSnVOLTS.
As a gamer, I can say that one of the things I miss the most about PC games is the ability to customize them to the fullest.
Dragon Age: Origins is no exception to that rule.
With the current version of this mod, you can use the left and right analog sticks on your controller to control your movement. You will not be able to move the camera and mouse at the same time. This is not a full controller, but it is a good start. I am not sure if you need to purchase all of the modules in order to implement this configuration.
