When you see [Everyone Hated That] pop up after your last choice, and you panic and try to load a previous save, but the game remembers what you already did.
Oh, that's a good point, I didn't think of it this way. I felt that Pathologic 2 handled it pretty well, because the first time I died, I was confused at how it framed the consequences (instead of a straightforward "you died! Load earlier save?", you get a conversation with an NPC that explains some of the consequences, albeit somewhat obtusely). The actual consequences of death felt surprisingly forgiving, given all I've heard about Pathologic (especially the first few deaths).
The original animal crossing had something like that. If you turned off the console without saving, a mole named Resetti or something like that would rant at you about how you aren't supposed to do that. The rant would get longer the more times you turned off the console without saving.
Undertale had this. It allowed you to reload the older save and undo what you did, but it kept a second, hidden save file that you couldn't easily erase.
