Your best bet is to take it to a gaming store and get it buffed .
Don't even take a chance of using tooth paste or peanut butter , just screws it up more .

That trick never works with the ring scratch like this, unles it is not deep at all
it usually only works when u have regular scratches from dropping it, rubbing it against something, etc.
and yea, id go get it buffered, its pretty cheap and saves you out of buying a new game.

go rent a game. Install it to hard drive. take back game. Tada your game will work

I would buy a new one but saving money so that when a new game comes out I can get it
