Games like Grand Theft Auto have a one-off protagonist. Zelda has Link. I prefer having new protagonists, playing as the same character can get boring. All though, sometimes I wish some protagonists got the same treatment as Assassin's Creed did with Ezio Auditore and his three full-fledged games by Ubisoft. I'm sort of glad there will be a new Witcher in The Witcher 4.
