The team discussed continuing the 2D strategy, which would have been the safe and immediate path compared to the radically new development paradigm behind the industry's imminent shift toward 3D gaming. The team took the riskier option to make a 3D game on new generation hardware, with their main choices being the cartridge-based Nintendo 64 or the CD-ROM-based Sony PlayStation. The team also considered the Sega Saturn console and Microsoft Windows. Their decision was influenced by two factors: a widely successful technology demo based on "Final Fantasy VI" using the new Softimage 3D software, and the escalating price of cartridges which had already limited Square's audience. Tests were made for a Nintendo 64 version, which would use the planned 64DD floppy drive peripheral though Nintendo had not yet produced 64DD development kits due to the prototype's changing hardware specifications. This real-time version was discarded during early testing, as the Behemoth monster's 2000 polygons placed excessive strain on the Nintendo 64, causing a low frame rate. It would have required an estimated thirty 64DD disks at about each to run "Final Fantasy VII" properly with the data compression methods of the day. Faced with the state of technology, and impressed by the increased storage capacity of CD-ROM when compared to the Nintendo 64 cartridge, Square shifted development of "Final Fantasy VII" and all other planned projects, onto the PlayStation with pre-rendered movies.
