Was just playing a strike game, and I noticed something odd about the game.
As you can see, 3/4s of the game has a blur/median filter effect. At first, I blamed my television since it has a long history of problems. But then I noticed the GUI is in perfect condition. I started to wonder if it was my PS3, but it wasn't even a year old. So then I took the disc out, and saw that there was a big, yellow, scratch. And a fingerprint. Cleaned it with water but that made it worse and then used window cleaner. It solved everything, so for those of you who have dirty discs, clean them.
It is interesting what a scratch can do. The rest of the disc was in brand new condition, but that one scratch caused this.
