I've been playing Fallout: New Vegas for 2 years. I've really enjoyed it. I recently popped in the disc for som good times. I started up the game. The left stick now causes my character to aim and the right stick causes him to move. This makes the game unplayable. How do I fix this? It also happened to my Fallout 3? I've tried the control menu but there's not anything to change the sticks.
