I'm actually pretty lukewarm on the Witcher franchise. I've read all but the most recent book, tried the show for 2 seasons, and played all the games. As much as people hype this franchise as some sort of rival to A Song of Ice and Fire or Lord of the Rings, it absolutely falls short.

That said, the Witcher 3 specifically deserves all the love it gets. I actually boycotted it for a few years after release because the graphic downgrade it had after the early gameplay trailers came at a time of extreme manipulation of this sort from other studios, but eventually picked it up with both DLC in a sale, approaching it with a lot of cynicism.

Not only does Hearts of Stone tell what I'd consider the best witcher story, Blood and Wine is a fantastic post-game to the franchise in its vibrant pageantry romp through a riviera; it's just a happy environment to end Geralt's story in.
