Some games do allow you to import saves from older games that have swapped the MC. They just take the choices you made in the story arc and use that to create conditions for the world you’re now in. But it’s a rare occasion from what I know.
You’re getting downvoted but I agree, to an extent. If it’s an RPG telling a grand story, and not an individual piece dedicated to a unique individual, then yes.
Over time the concept of the downvote lost its meaning, even on Reddit (and that happened a while ago).
Sadly most people just downvote when they don’t like what you’ve said, not if it’s factually incorrect or misinformation etc.
