I love do over stories. I have noticed just about all of them have the MC going back to the 70's or 80's to their teenage years. I would love to see a story where an older MC goes back further to relive being drafted or volunteering for WW2 or maybe Vietnam. Where the MC is able to fix battlefield mistakes that they made the first time through and maybey becoming a hero and then getting out of the service and becoming rich and famous or just rich.
