For me this is the best Single Player game, I've ever played.

Storyline - 10/10
Story is presented in a very nice form. In most of the dialogue you can choose what to say. We have many ways to pass the mission. We can do it quietly or killing everyone. Each mission is interesting and different than earlier. The story is for 30h game without sidequests. We also have mini games like cards (Gwent).

Gameplay - 9/10
Beautiful world giving many opportunities for the player. We can explore caves, forests, mountains, helping peoples and doing much more things. The map is 30 times bigger than in the previous part. Crafting and Alchemy are more important, we also can upgrade swords, armors and signs. These sandbox gives many, many opportunities. Fight feeling is pleasant. Sometimes we are blocking on a small obstacle but in comparison to other games it is not very annoying.

Characters - 10/10
Each character has its own charm. Characters are well matched to the storyline and to the environment. We can decide who will be our enemy and who is our friend. We also can choose the path of the main character. Character (mainly Geralt's) and monsters doing really great feeling, details are amazing.

Graphics - 10/10
Graphics in this game is amazing. Even the smallest details are well refined, for example when we move the grass moves with us. Graphics capabilities used in 100%. The movement of water clouds are very well refined, falling leaves, changing weather make a huge impression.

Sounds - 10/10
Music and ambient sounds in this game is great fits. We can listen medieval music which is selected for each moment of the game. Animals noises are natural. The monsters sounds are really threatening. Character voices are well selected and fit into personalities.

Overall - 10/10
If you are thinking about purchase this game, if you like open world and action RPG games, I would recommend these game for you, and I guarantee a lot of fun comes from that game. These game is masterpiece.
