Andrzej Sapkowski, the author of The Witcher series, is a very matter-of-fact man. He doesn't beat around the bush when doing interviews, which comes across as both biting and refreshing at the same time. In a recent interview with io9, Sapkowski was asked about how the Witcher TV show compares to the video games. Check out his response below.
I cannot compare anything to video games, because I have never played any. Since I was a kid I haven’t played any games—with a possible exception of bridge and poker. Video games are simply not for me, I prefer books as entertainment. Anyway, in my opinion TV series and video games—any of them—cannot be compared. They are too different in approach, making—and objective. You cannot compare spaghetti carbonara with a bicycle. Even though both have advantages and disadvantages.
