Metal Gear Solid 4: Guns of the Patriots is so big that it wouldn't even fit on a Blu-ray disc properly.
That's according to series creator Hideo Kojima, who told Famitsu that cuts and compression were necessary despite having 50GB with which to play.
"For us, we're not still not satisfied with the quality we can do. You know, there's not capacity space," he told Famitsu in an interview partly translated by Kotaku.
Asked to clarify, he added: "There's not enough space at all...There's not enough space. We always talked about where to cut and what to compress."
Last week, the assistant producer Ryan Payton told the Kojima Productions podcast that the Japanese voice-over would not be included on the America and European disc due to space issues.
Then again, that Blu-ray does have to hold both Metal Gear Solid 4: Guns of the Patriots and Metal Gear Online.
As announced last week, Metal Gear Solid 4 will be released on 12th June worldwide, with a beta test for the Metal Gear Online - due at the same time - set for late April.
