I can confirm that since KISS, ALL distributors are required to to unbox ALL games for quality assurance. It is mandatory.
I'm not sure who's right or wrong (although I can only see 4 members posts shit I love the ignore feature) but having said that I've had all my games checked ( they travel along way) to sort any issues before I open it and I've been happy doing it this way. I personally think it should be the buyers choice but understand why AMD like to open the games. I've heard some funny stories about buyers demands lol
