I was under the impression you could make more than one save file. Weird.

I do wish that I had check out more of the side quests, but by that point the game had repeated the same side quests without any new content so I was hesitant to try again. For example, the Monk/White Mage fight came up in chapter 5, was great with new dialogue and fleshed out the two characters a bit. Chapter 6 and it's just the same dialouge from chapter 5 but they had increased the difficulty slightly. It's at this point I opted to not do the sidequests again as there didn't see any point. I am sure I fought the Bloodrose Legion though.
