3 discs? Try 7 or 8. MGS4 used 50GB, and 75GB to 100GB discs are just around the corner. Eventually, BluRay disks will reach 150Gb to 200GB.
For other genres, especially shooters, which are linear experiences featuring the same dusky, dreary slab of battlefield red-brown-greys, the extra space doesn't matter. But for RPGs, which require huge, immersive and expansive game-worlds which the player has the freedom to explore as they wish, the lack of storage is a deal-killer. Reason: every new location requires you to backtrack to a particular disc. Instead of changing the disc every ten hours, it will be more like every ten minutes, especially later in the game.
