I managed to come across a very rare auction on eBay last week for an extremely early development copy of "Final Fantasy VII" from 1995-96. This disc contains the much talked about Siggraph works as well as an actual playable game with whatever they were working on at that time. Apparently this is the earliest playable demo for FF7 and is supposedly extremely rare and one of the hardest to find (and maybe one of the rarest in the series). It's supposed to come by the end of this week and I can't wait to play it.
Here are some pictures of the game:
