How hard would it be to set a World option so that instead of keeping it or resetting the entire world, it keeps the locations, a la the save-scumming Vormithrax did on his groundhog day series?
Essentially, he saved immediately after the first turn, and then reloaded from there every time the character died. So instead of a complete reboot, the world was familiar.
I assume it would take different amounts of coding to keep the same items everywhere, versus the same buildings but with new variances (different layouts for the same building type in each square, etc). Which would be easier to mod in?
