I’m a casual gamer so perhaps this has been made hundreds of times and I just ignore it.
So let’s say you play your game, things don’t go well so you go back and reload a save. Now, with your current knowledge you can get things right and that’s usually how it goes with games.
Is there any game that takes this into the plot as something necessary by design (say for example, the main character is supposed to be clairvoyant or something)? You play, your character gets things wrong the first time, but now when you reload your character will obviously do everything right, almost as if they were clairvoyant/psychic/etc because that’s exactly what your character is. The only way to beat the game is to explore a variety of outcomes in order to gather information until you get it right, but instead of this being immersion breaking it’s actually supported by the plot itself.
Not sure if I’m making sense here or maybe I ate the wrong kind of cookies, you tell me…
The Demon/Dark Souls formula is essentially this. The idea that (depending on the game and boss) you actually canonically tried and failed countless times before finally winning. I want to say there is an indie game that is approaching that from the perspective of the boss (Many a True Nerd did a video on it. it looked “fine”).
Warframe has also played with this in a different way. The 1999 update is about a time loop where you get to know (and romance) the characters involved. And over KIM (like AIM but legally distinct!) they outright acknowledge that they don’t know how many loops have occurred but trust you about it and blah blah blah.
And Undertale/Deltarune and Doki Doki Literature Club (among many others) also play with this to some degree.
But ACTUALLY keeping track of when you reload a save? I am not aware of any. Mostly because it would make the mechanisms that save files work by MUCH more complicated.
No, I’m not saying keeping track of when you reload a save but simply have the NPCs and maybe even the main avatar acknowledge they know exactly what would happen if they did things differently, because they’ve already experienced it in another timeline.
You wouldn’t need to keep track of saves, just leave some dialogue lines that vaguely address this after the fact.
