Here's good news for you Final Fantasy players out there: The demo version of RPG Final Fantasy XIII is said to be over 90 minutes long.

Japanese gamer bible Famitsu is reporting that the playable game preview included with the purchase of the Final Fantasy: Advent Children Complete DVD will last longer than the film. And the film is over two hours. Hence: Very long demo! Supposedly, the demo will cover the very beginning of FF XIII, so no spoilers, either.

The DVD is scheduled for a March of 2009 release in Japan, and will contain HD trailers of Final Fantasy Versus XIII and Final Fantasy Agito XIII, making them the first released trailers of the Fabula Nova Crystallis series. No word on a North American release yet.

Final Fantasy XIII is scheduled for some time in 2009 for the PS3, 360 and maybe PC.
