What is the Witcher about? Never played the games. I know it's very popular and seems like it's fantasy and you can fuck people. That's all I've gotten from the zeitgeist.

The Witcher focuses on the titular character, Geralt of Rivia and his allies while they hunt monsters and get caught up in other shenanigans. I haven't played any of the previous installments or read the books but in Wild Hunt, the plot revolves around trying to find your adoptive daughter before the titular antagonist does and along the way you find yourself drawn into a few different political plots and numerous other side quests. 

Oh and you can have sex by romancing four or five different companions or you can pay for it at various brothels. Each interaction comes with a gratititous cut scene. Most are pretty generic but there's a few unique ones.
