At a pre-Tokyo Game Show conference, Mistwalker’s Hironobu Sakaguchi revealed new information about the developer’s upcoming Xbox 360 JRPG Lost Odyssey.

One of the most surprising details Sakaguchi, the creator of Final Fantasy, mentioned pertains to game length. He estimated that Lost Odyssey will take 40 hours to beat and includes 20 hours of event scenes. Essentially, it’s Xenosaga on steroids.

The game has a deep backstory, with the cursed main character having lived for no less than 1,000 years, and many event scenes explore his accrued memories. Interestingly, much of the backstory is explored via passages written by Japanese author Kiyoshi Shigematsu.

According to Sakaguchi, there are 34 written passages, and each takes between 5 and 10 minutes to read. That means as much as 6 of the game’s 20 hours of event scenes are reading.

I understand that a good story needs depth, and many a good game employ writing to explore it, including the recent Oblivion with its library of history books. But Sakaguchi may be going to far with this, entirely divorcing gameplay from what may be necessary developments in the story. It will be interesting to see how this game is received.

Lost Odyssey will release in Japan this December.
