To be honest I’ve only played MGS3. I thought you were playing as a clone of the boss, reliving the original’s life? It might have just been a theory video I watched. I do remember dying in one of the later boss fights and the fail screen rearranged itself to say “time paradox”.
If anyone is unsure about it and owns Minecraft, check out the TerraFirmaCraft mod. Vintage Story and TerraFirmaCraft are both based off the VintageCraft mod afaik
