The game is quite short (about 5 hours) and the ending may (or not) leave you disappointed, other than that a great, visually pleasing, story driven game about loneliness, dealing with change, acceptance and weight of responsibility and you know.. life :) 4/5 definitely worth it's discounted price.
If you are into story driven games, cards and puzzle solving this game is for you. If you happen to play Gwent, enriching your card collection is an added bonus, but I would buy it even if you have no interest in Gwent. Story is solid and it fits really well into Witcher universe, there are many memorable characters, some hard choices to make and you are getting solid 35 hours of gameplay! For a person like me who happens to be Witcher's fan from before anyone thought about making it into a game (yes, yes I'm a boomer) it was a really satisfying game to play, thanks CDPR :)
