Just a quick heads up for all you folks planning to play the Final Fantasy XIII (PS3, Xbox 360) demo. As it turns out, the demo will take up about 5GB of your HDD. If the demo's already demanding that much, imagine the size of the full game. Yikes.
Square Enix has not been able to give an exact value for a required install. While it's easy to say that one can always go get a bigger hard drive, it's even easier to see that those things don't come cheap. While PS3 owners worry about HDD space, the Xbox 360 version may take up more than 70 discs.
Of course, thinking about the full size and basing speculation from the demo is not the best way to go about it. It does make you wonder though, how big will the actual game be?
