Just completed the main quest in W3 (as well as all the contracts and most of the sidequests).
Guys, this game is a ****ing masterpiece.
Its not necessarily a "deep" game. The actual RPG mechanics and combat are fairly shallow. But GOD DAMN this game is cinematic, its immersive, its grimdark as **** (in like the most slavic way possible), its rich on lore, and it knows how to present its main cast in an incredible light. Go in understanding what you're getting and it will be one of the most rewarding gameplay experiences of your life.
Easily one of the best games of all time and worthy of a "Flawed Masterpiece" award if there ever was one.
I am going to count Hearts of Stone as well as Blood and Wine as their own games given the breadth of content available there.
I think I ultimately got the "Witcher" ending for Ciri, with her basically joining Geralt for a life of Witchering after the main game was complete. Maybe not the best outcome for the world, but by far the best outcome for Geralt and Ciri and I am happy.
