What would you want the next game to be about?

Title says it all. While we're all waiting with baited breath for The Witcher 4 which I'm certain is going to knock it right out of the park I thought it would be fun to talk about what sort of Witcher games we'd like to see CDPR make next.

Personally, I always thought it would be absolutely fantastic if they made a Witcher game prequel that revolves around the witcher massacre that Vesemir survived when he was younger. The games have hinted a few times that it was more than just a simple uprising(sorry need to admit that I'm one of those who have only played the games and not read the novels) so there would be a lot to explore and it would add more depth to both Vesemir's character and the Witcher world in general. You would either play as Vesemir or(my preference) you could create your own witcher survivor including which school you belong to which would effect your starting position in the world, equipment, and how other people react to you. Vesemir would still be a major/central character of course.

What do you wonderful people think? What would you like to see with the next Witcher game?
