hi :) you dont need to replay chapter1 if you have a good save right before it's end since there are no choices to make between guys there. after chapter1 the required amount of crafting is reduced. chapter2 starts the split, so for most of the guys you will need to make seperate saves from the chapter's second part. atm something like god mode is not intended, maybe it will be considered after all the 9 chapters are finished and released.
