That was pretty cool. The Sega Fantasy ones are really good as well. There's a lot of Japanese to read, but worth watching.
The ongoing theme seems to be current gen + last gen machines rising up against Sony and the next gen machines. There's also some interesting and imo wittycommentary about the video game industry in the form of character dialog.
Anyway, check it out especially if you're a final fantasy fan (before PS1 vers).
