Despite the extremely overdone color and contrast, and resulting depressed low-light visibility, Blood and Wine is brilliant. I suppose it helps that I get into the whole Boorman's Excalibur, chivalric-knights atmosphere that permeates it. Even without this tilt, the story and all the different consequences of the player's actions are, I think, without peer. Its world is gorgeously realized, from the scenery to the characters. It is so magnificently well-crafted. Shame that the underlying mechanics and software tech are in need of so much spit and polish. Nothing worse than the vanilla game's problems, though. I lived with them then, and managed to live with them here again.
Anyone who likes TW3 absolutely needs to play this. I played Hearts of Stone and B&W in quick succession, and while HoS is good, it's absolutely dwarfed in both quality and quantity by B&W. I do recommend playing both for the unique expansions to crafting and abilities.
