Yes but even in most video games, when you respawn you don't have to start from the beginning each time. You start from where you die or a save point.

You're right; most games are like that. But that is one of the defining features of the roguelike genre. And even a lot of those don't use "respawning" the way others do. They are intended to convey that you are an entirely new adventurer because your last one died. Hell, a lot of 'em even allow you to encounter the corpses of your previously fallen characters. Like Pixel Dungeons or Project Zomboid.

I'd like to see some shows that do it. I hadn't heard of Severance, so I'll probably check it out just because I do find it an interesting concept.
