I'm a pretty avid player, and when I play, I play for hours... and I don't mean 4 or , I mean 8,9 or 14 hours. Never had I played that the ring happen, my nephews as well. The only time it scratched anything, was when the 360 was moved from a laying to a standing position. If it's just regular scratches, then who knows, maybe I don't know abuot those. But the large rings are from movement. so for those... yes, it only happens to idiots.
