Ok, i have halo wars for the xbox 360, and sometimes when you start (when choosing between which character to use, 1v1,2v2, or 3v3) well when i press start or the A button or B button, it's non responsive! Does this happen to most of you guys (nothing is absolutely wrong with the controller, it works perfectly fine with every other game, the xbox 360 works great, and the disc is 100% clean) =( help!
