What would the possibilities of a game mode I like to think of as Ironman.
I’ve seen something similar with other games where there is no auto save. Additionally, each time you open the game the existing save file is essentially locked so you can’t run off a save, have something go bad, and then go back and reload it to try again. You have to to a formal save to leave the game and the previous save game file is over written.
I understand game crashes happen and could be an issue , but with sandbox games like this it makes a player think through their actions and suffer the consequences of poor results.
