Hmm, now that you mention it, having multiple save files on hand does tend to get confusing after a while (I tend to keep one page of saves per character, but even I had a feeling that wouldn't be enough). A way to differentiate them might help.
But I think it's got me wondering about another thing:
With how far along the story is now, it kinda makes me wonder if a Chapter Select system could be implemented, if that's even remotely possible...
