[quote name='Indiana Jones']Okay, I'll bite. Of all the games the 10% coupon isn't valid for... Far Cry 2?[/QUOTE]
Far Cry 2 is free with the purchase for a 360 Slim Arcade, so I think it was causing some conflict in the computer. Or they were just worried about running out of Far Cry 2's (giggle) to give away during the promotion.
