Hey! Is the PS3 version of this game on a dual-layer disc or single-layer? To check, you can look at the shiny part of the disc, and near the center there should be some code. If it says "BP-DL" it's dual-layer, if it says "BP-SS" it's single-layer.
I ask because my PS3 has difficulty reading dual-layer disc and if I can avoid the hassle of reinserting the disc some 30 times while lifting my PS3 disc-tray up, I'll probably pick this up tomorrow.
