some third-party developers switched to the playstation. this includes square who had produced a "final fantasy" technology prototype using the same sgi-based development platform used by nintendo, and enix whose "dragon warrior vii" was initially pre-planned for the nintendo 64 and its yet-unreleased 64dd disk drive peripheral at least by 1996, but reluctantly migrated due to the developers' increasingly ambitious use of storage space with their fundamentally cinematic game format. shiny entertainment had been planning to develop "mdk" for the nintendo 64, but switched to pc when they found the cartridge space was insufficient for their plans for the game and nintendo failed to produce the promised 64dd in a timely manner.
