After playing the games this was just a beautiful gift from the creators to the fans and also to the people who watch Netflix this show defines excellence.
Don't worry if you not played the games or read any of the books you can watch it. It has some intense drama and action which kicks off right from the start. The story ties in beautifully and the cast do their characters justice especially Henry Cavill who after watching looks like he was born to play the Geralt he has many similarities to the witcher from the game which is good.
The CGI is very detailed and looks stunning. Netflix has put a lot of effort into this and it shows.
Kudos to the writers because the way they portrayed the story was good as it was really difficult to maintain all these characters and tell a compelling story at the same time they did great.
