but excellent version of a game like The Witcher 3, which is nearly a full decade old. I'm sure CD Projekt will be more than happen to lay a claim to the re-release crown that keeps being traded back ...

Witcher 3's Ciri will become the one from Witcher 4 ... there shouldn't be a lot of problems if you're careful. There's a reason Skyrim players tend to list their mod count in the hundreds.
