The Video Game Critic

I don't know if someone could answer this. Did Sony stop putting the ring of playstation 'P' logos on the outer edges of the undersides of discs with later games?

I ask because I purchased a sealed copy of Twisted Metal Extra twisted edition and it lacks these? Though it does have 'playstation 2' written on the inner ring.

Ok, I've had another look at the disc and the ring of playstation logos was there all along, just they were extremely faint. Sorry.
