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.
While it doesn't offer much in the way of closure, The Forgotten Sanctum is a satisfyingly eccentric expansion with Cronenbergian elements and an atmosphere vaguely reminiscent of Planescape: Torment.
Seeker, Slayer, Survivor plays like filler DLC. It's below average and lukewarm at best, with very little of what makes an Obsidian RPG in the mix.
Even if you can get past the countless technical issues, Underworld Ascendant is a poorly designed abomination that ruins the Underworld series even to those who've never heard of it. This is the final nail in the Immersive Sim™ coffin. Bury it and salt the earth.

Phantom Doctrine is a life-consuming espionage simulator that offers a deeply complex cluster of systems to explore. Its turn-based tactics gameplay is a feat of engineering that will offer players many hours of combat thrills and stealth schemes.
