Okay thanks for the response but I'm not sure how it answers my question. If I am playing on chapter 7, but I'd like to go back to chapter 3, while still saving my stats from chapters 1 and 2, will that work? Or wil it reset my stats as if it's a new game? Sorry I know it's kinda a weird question but I know one of you **bleep** knows the answer haha
*Edited for Clarity
The only thing you have to worry about when dealilng with multiple save files is your progression. Just make a seperate savefile for whatever reasons you're going back to chapter 3 so you don't lose your progress up to chapter 7.
