I love the hell out of The Witcher 3. It's easily one of my favorite games of all time. That said... the Witcher 3 didn't have particularly complex quests. The story took some cool turns, but the quest structure itself was relatively simple. The Witcher senses for example, were very simplistic and boiled down to following scents and footsteps. Most of the time, with one or two exceptions, the clues to followed in questlines could never lead you astray or cause you to make a regrettable decision, like accusing the wrong person or whatever. Under the surface, Witcher 3's quests really weren't that complex at all, so while I am glad to hear Cyberpunk will improve on that, it's not saying a whole lot.
