What do you like about Unfinished Business? I found them excessive and dull, or blazing clear examples of why game content should be cut. Instead of the usual "it's shit", I'll break it down since I need to procrastinate doing something else more productive.
The Kidnapping of Boo, by Cliffette : BSB if you're like me and think Minsc is one of the worst characters to ever exist in a game. Obviously going for the Chuck E. Cheese crowd (kids, for you non-Kwas) with the addition of Boo. A rather involved quest and not too herp-derp in its layout, but it's worse than a Disney movie in content.
The Suna Seni/Valygar Relationship Restoration: Ever had Valygar in your party early enough to encounter Suna with him? Yeah, that's a problem if you want to experience the vanilla dialog that reveals that they were once an item. This component adds in more overwrought fan-fiction dialog that adds zero to the game. Despite this, Valygar remains uninteresting. Subtle? Introduced with grace and humility? No. A sample on their first meeting:
Suna: "Valygar?! Valygar, is that really you?"
Valygar: "Suna Seni! Oh, how I have longed to see your beautiful face once again! I have missed you so much since I fled the city. I am sorry I had to leave you so suddenly and without explanation. It pained my soul to know that I might have hurt you."
Kalah and What He Was Promised, by Andyr Terrible. You walk to an inn and fight a rakshasa. Oh, and the free rep point. I can't find anything in the original that justifies any of this. Apparently because one of the illusions was a djinn, that was stretched into this mess of Kalah getting this power via 3 wishes. Tripe.
Cat and Mouse: Bodhi hunts you in Spellhold, by Ghreyfain: Not bad and in the same vein as the Tougher series that restored the difficulty of the major ToB battles. Hardly something that qualifies as "unfinished" but whatever.
Gorje Hilldark and the Extended Illithium Quest: Getting the illithium already bordered on tedious. If you'd like to spoil a semi-major side quest's area and shove a good 30 minutes of mindless dialog click-throughs into it, this is for you.
The Pai'Na/Spider's Bane Quest: Basically a dialog-only addition, but it's real value is making it possible to get Spider's Bane again (which is otherwise unavailable in SoA... I think).
Restored Crooked Crane: Great! Finally the story of the pair upstairs makes a bit of sense. There's even some C&C later on.
Restored Encounters: A mixed bag, this. The extra two thief/vampire brawls don't add anything beyond more "Why aren't the guards intervening? This is serious." from the player. Hell hounds restored? Okay. And the vengeance seeking fighter still looks like half-assed content.
Artemis Entreri in Bodhi's Lair: But only if you have Drizzt as well? Shouldn't it be the other way around? By now you can tell that what qualifies as "unfinished business" is tenuous, at best.
Corrected "Xzar's Creations": A bizarre and extremely minor creature substitution. I guess calling the mod "Superfluous or Cosmetic Changes We Wish Could Be Thought Of As Semi-Official" was too much of a mouthful.
Restored Hell Minions, by SimDing0: This would be better served as an option in the Fixpack, or Tweaks failing that. Before SCS, there was Tactics. In between, there were AI+creature guys like Sim doing good stuff like this.
Gorf the Squisher Fix, by Gebhard Blucher: Deprecated by Fixpack.
=== I'm about 2/3 through. There's one component I'd recommend, the Restored Bhaalspawn Powers in ToB, that gives you back your BG1 innates. There's also a serious decline component auspicially named
Sarevok's Remorse for Yoshimo and Tamoko. Skip it unless you think DA2 is a masterpiece of storytelling. Most of the others are deprecated or just whatever, but none qualify as the mod's title.
You know what unfinished business didn't get taken care of? Haerdalis stealing the bust of Sune from the merchant Qataris.
