Here's an interesting fact: if you remove all the sound files from Introversion's brilliant DEFCON, the game comes in at around 4MB. On the other hand, Hideo Kojima reportedly had trouble getting Metal Gear Solid 4 to fit within the 50GB limit of a single blu-ray disc. Now, we're sure that every single drop of MGS4 is vitally important, and there's absolutely no chance that over-indulgent and ridiculously lengthy pre-rendered cut scenes have anything to do with it, but - 50GB? Not enough?

For comparison, our meticulous internet research has revealed that 50GB is roughly equivalent to 50 pickup trucks filled with books or approximately 35,000 3.5 inch floppy discs. And we thought the four 5.25 inch disks that Ultima IV shipped on back in 1985 was excessive.
