Actually... what happened in a game was practically a wild hunting... first to find Ciri, then it was a hunt against The Wild Hunt... taking out Imlerith, Gael, Caranthir and finally Eredin... CDPR nicely played with the game name, yet some people make incorrect assumptions on it, as if the game was supposed to be more about The Wild Hunt, because it has Wild Hunt in the title...
and yes, i think player got enough of info in game, plus, there is a whole novel written about it, so whoever wants to know more, can just simply buy those books and read them... Books are not really needed to play the game, but are definitely needed if you want fully understand the story.
and i can guarantee you that so far, nobody who liked the games and then read the books was dissatisfied with what Mr Sapkowski wrote..
