June 7, 2011
Konami revealed at its E3 press conference that Metal Gear Solid Snake Eater 3D will require a game card double the size of a standard 3DS game card.
Hideo Kojima's 3D creation will ship on a 4GB card, when most 3DS cards are 2GB. Whether that means the game will be twice as good as anything else on the platform remains to be seen.
