A Woman's Lot is a rewarding coda for Kingdom Come: Deliverance that might make you itch for a new playthrough. It features two tense questlines where you'll survive the Sack of Skalitz as Henry's love interest Theresa, and help the devout nurse Johanka in her complex theological conundrum.
Months after the final release, Gwent: The Witcher Card Game is still going strong. The minigame-turned-esport continually goes through iterations and patches, shedding skins and morphing into a real beast of a card game. It has a wistful past, a solid present, and a bright future.
The Amorous Adventures of Bold Sir Hans Capon is a bundle of glorified side quests that you might enjoy if you already enjoyed the base game quests featuring Hans Capon and the Charlatan of Sasau.
From the Ashes meshes well with the base game, and it might help you discover some overlooked side quests. The village building and management is interesting, but ultimately superficial. The conclusion feels somewhat anticlimactic.
