I play RPG games on PC since c.a. 1990. The Witcher 3 is one of the best games i have ever played. The base game i would give 4/5 stars, but the Blood & Wine expansion is absolutely fantastic in every aspect and deserves 6/5 stars. 100% recommendation!
One of the best games in this category since Baldurs Gate/NWN. I can't find any bugs atm, so it seems that they fixed a lot. Very good appliance of the Pathfinder rpg rules. It is shurely an advantage if you know this rules. Lots of possible caracters to create. The game ist quite hard for for this day and age, and sometimes you have to load a savegame oder avoid an area until you are at higher level. But i can recommend it for evreybody who likes Baldurs Gate/NWN/Pillars of Eternity/Divinity etc..
