So, completely random thought just popped into my head.
Has there ever been a series, anime or live action, that toyed with the idea of traveling back in time in a similar style to a RPG save file? Like, if they decide to record a certain day as their "save", they could return to that moment as many times as they want until they decide to "save" again.
I'm sure someone could point out some flaws like "why would they want to overwrite the "save" they have if it means it'd skip some events they might want to experience again", but I don't know, just a weird thought considering how many anime/manga/etc. like to toy with time travel like Steins;Gate, Girl Who Leapt Through Time, etc. & also how they like to make fantasy RPG parodies.
