Final Fantasy VI: The Interactive CG Game, aka Final Fantasy 64 (Unreleased 1995 Tech Demo)

Before Squaresoft (now Square Enix) made their move into the realm of polygonal 3D gaming with their critically acclaimed Final Fantasy VII, (originally released on the PlayStation in 1996, then later on PC), they were experimenting with developing a Final Fantasy installment for the next-gen consoles. The result of this was a small playable demo, showing off the then-new technology, titled Final Fantasy VI: The Interactive CG Game, though it has come to be unofficially known by many as Final Fantasy 64, as the result of a rumour originally published in an October 1995 issue of GameFan Magazine, which claimed that the demo was taken from an upcoming Final Fantasy game, supposedly in development for the upcoming Nintendo 64 (then-called the Nintendo Ultra 64); said rumour was incidentally discovered as being completely false and unfounded upon Final Fantasy VII's PlayStation release. In the end, Squaresoft's decision to develop for the PlayStation rather than the Nintendo 64 simply came down the fact that Nintendo 64 cartridges had significantly lower storage space, when compared to CDs.

The demo was unveiled at SIGGRAPH '95, (which took place in August), and featured the three playable characters Terra, Locke and Shadow, (originally from Final Fantasy VI, which was released in North America as Final Fantasy III), showcasing a re-vamped battle system, (which would go on to be largely incorporated into Final Fantasy VII), with the group fighting a rock golem. It ran on an SGI Onyx visualisation system, a powerful computer, (at the time, at least), specifically designed for intensive 3D modelling, and the characters were controlled by drawing a variety of different shapes with the mouse cursor, (each shape representing a different action).

A recording of the SIGGRAPH demo taking place was subsequently released as an extra on a demo disc for Final Fantasy VII, and has since become widely available online; however, the playable demo itself has yet to be released in any form, and is largely sought-after by fans of the Final Fantasy series.
