The big thing to remember about the Witcher franchise is the book writer only cares about one thing.

Money.

He took a lump sum from the original games at first because he's a boomer fuck who despises games and thought they would flunk.

After the games became more popular than the books, and let's be honest are without a doubt the reason the Netflix show got made because the books were not popular enough on their own for that despite the current trend of medieval larp shows after GoT, he sued them for more money and ended up winning which pissed off a lot of the game playerbase.

He's since spoken very favourably about getting more money the Netflix show because it gets him more money of how well it makes him more money it was written despite the massive backlash from;

Normies: Even those without book and game history think the show is badly written regardless of the lore problems.

Book readers: The show fucks up so much it's worthy of literary thesis work.

Gamers: RISE UP! Various "defences" about the show are how it is a "loose" adaptation of the books and not the games. Which was proven to be bullshit in season 2 when they brought in "Lambert" then killed him off soon after because the showrunners wanted to create an impact. Except Lambert is barely in the books so the only ones this will register with is the gamer section of the franchise despite that group being told more or less that the show wasn't for them.

But again, all he cares about is money so even when [yes "when", not "if"] more shit live action adaptations [they're making prequels now] and games are made he won't care because he still gets paid.
