In an exclusive interview with Hideo Kojima, the creator of Metal Gear Solid series, has made complains about 50GB BD not been sufficient. The Metal Gear Solid producer considers the Blu Ray disc too small and that they had to make compromises in order to put the game on the 50GB BD. According to Hideo, the programmers had to compress some parts in the game to save disc space.
Kojima : I am not satisfied with the quality yet, however...there isn't enough space.
Interviewer: Not enough space..on..Blu-ray..?
Kojima: Yes.(laughs). Not enough space.
