Lets remember what started this whole debacle:<latest large post>
So no, there really is no reason they have to be on a blu-ray. Theres no reason we all couldnt still be swapping cds every hour of gameplay. But silly me, i like convenience and high-end electronics. Silly me, always wanting the best.There's nothing so special about the PS3 and it's games that made it 100% necessary to put games on BlueRay discs and not on DVDs.
Sure, SE could have made FF13's cutscenes look the same on the 360, but it would probably take an extra 2-3 dvds to do it. Then you go from swapping every 15 hours to every 6-7 hours.
