Xbox 360 owners hoping to sit down through a whole playthrough of Final Fantasy XIII, be warned. Final Fantasy XIII producer Yoshinori Kitase confirmed today at GamesCom that the Xbox 360 version of the game will ship on multiple discs.

“This is not the final count as we’re still working on it, but we’re aiming for about three discs for the Xbox 360 version,” said the developer.

Games like Star Ocean: The Last Hope and Lost Odyssey went up to even four discs on Xbox 360.

Kitase also did mention that both versions of the game will be practically identical, although there will be those “subtle differences.”

“The 360 version and the PS3 version should be pretty much equal, both in terms of content and the visuals as well,” he added.

“Since the hardware is different, there might be some subtle differences if you compare screenshots side by side, but the team’s being very careful about the compression of the data and the visuals, so that it’s exactly the same on both.”

Final Fantasy XIII is due to launch in Japan this year with a North American and European release to follow Spring 2010.
