If there's a safe choice for the best quest in The Witcher 3, it's probably the Bloody Baron storyline, a dark, harrowing, morally nebulous about a local lord meeting the consequences of his own domestic abuse. This was, in fact, the first thing that quest designer Paweł Sasko built for The Witcher 3, and it already had a massive script before the dialog was even added.
"Family Matters, Bloody Baron’s story, was the first quest I designed for The Witcher 3, on outline by Marcin Blacha," Sasko says in Twitter thread reminiscing over his time at CD Projekt Red. "First script was ~40 pages long, just the plot, no dialogs yet. Used Slavic folktales about botchling and lubberkin to enrich quest about domestic violence."
