Ok so I got a second hand PS3, and on there is a saved data for FFXIII. And where it usually displays the chapter title, instead it says "The New Dawn".

I'm just wondering what this is? Is it a special chapter? Does it mean the person beat the game and completed the last boss? Just curious really...

Anyone?

Yeah, I'm pretty sure that's a post-completion save file, because FFXIII allows you to go back to Gran Pulse after beating the final boss and do side quests/missions you might have missed (it's also the only way to unlock the final level of the Crystarium as well). My guess is that is indeed a 'game complete' save.
