i had to go thru two copies of the new gears of war judgement to find this out. i tried everything to get it to play, and it wouldnt work. but my other games would. so i got thinking, maybe it WAS the HDD. i had read somewhere that they will go out with similar issues occuring thereas. so luckily, i had a previous 360 which fell victim to the red rings. 3rd one like that btw, lol. good thing i had it on hand, cause i swapped out the HDD's from the old one to the new one and the game works fine, not a problem at all. so if you have this issue, and returning the game for a new one dont work, its time to replace your HDD. i lost a lot of save data, but nothing i cant get back. hope this helps.
