Ah, wasn't aware of that. I thought all discs were region-locked when sold like that. Learn something new every day.
Yeah i didn't know this until a few years ago. I have 7 360 games that are PAL region games but play on NTSC consoles. A LOT of shmups. 360 has turned into one of my all time favorite consoles due to this. --- FACT: Demon's Souls: rpg of the millennium
