Update: I finally finished the game, albeit on a second playthrough. I had gotten as far as the entrance of the House on my previous playthrough, found myself bereft of all my party members except for my Mystic Theurge who replaced Tristian (quite well, I might add), and threw in the towel when I got majorly bad vibes off the whole thing. I might try to go back and salvage that game, or I might not, but is it worth the effort? Probably not.
Second playthrough:
I left Kingdom Management on Effortless, and still got frustrated with how much crap requires you to sit in the throneroom and do nothing else for 14 days, and how certain problems crop up riiiiiight when you're trying to upgrade an advisor (which takes too long) or annex some territory (which also takes too long) etc. So I got annoyed and installed a mod that lets me resolve anything in 1 day and I easy-streeted it for the rest of the game. In theory that mod + auto mode may produce some really nice results, except for the fact that auto never builds teleport circles (I guess?). Teleport circles make Puja the Wolf's quest actually quite easy. Just use that plus the Heart of Ira and it's an easy win.
Anyway second playthrough, Normal mode:
Valerie/FakeValerie (Shield Specialist 9 Stalwart Defender 10)
Bishop Bruiser (standard Cleric of Gorum 19)
Nok-Nok/NotNokNok (Knife Master 19)
MetaDruid (main) (Defender of the True World 19 - Smilodon)
Linzi/FakeLinzi (Bard 19)
LameSorc (Sylvan Sorcerer 19 - Smilidon)
Immediately prior to entering the House, I replaced all my story-mode NPCs in rotation with mercenaries made to ape the originals faithfully. Only major differences: FakeValerie starts with 13 Int instead of 15 Cha, so she can get Combat Expertise honestly; FakeLinzi has slightly different stats which proved irrelevant in the end; NotNokNok is a Tielfling instead of a Goblin so he loses 2 points of Dex and the small-sized race benefits and gains in some other areas. Also I changed NotNokNok's Rogue specials a tiny bit, but not to any major extent.
Bishop Bruiser is a respin of my main character from the first playthrough. Instead of using Crusader, I went straight Cleric, and I went straight for fauchards once I found a good one. Overall he came up short on a few feats (no Heavy Armor proficiency; he had a +5 Breastplate of some kind instead; no Weapon Focus on anything; no Armor Focus), but I used my knowledge from the first playthrough to buy into Combat Reflexes (after I found him +6 dex stuff) and Sieze the Moment which I never did with my main from the last playthrough. Big improvement in damage output when focusing the same target as the party Rogue.
MetaDruid is just a boring Druid buff-bot with a Smilodon. He spent most of the game throwing darts to stay out of the way. Wildshaping was . . . unimpressive. All I did was start with high Con and high Wis, and high enough Int to get Combat Expertise (which I wound up never using), and uh that was about it. Most of his feats were kinda wasted or forgettable "anyone can use that" stuff like Shake it Off, Toughness, Allied Spellcaster, etc. I picked up Spell Focus: Transmutation but never used it much when it turned out that Baleful Polymorph is buggy as hell and can prevent looting. Was gonna use Heighten Spell to have a ton of those prepared, and honestly it might have been a good idea against some of the things in the final dungeon, but in the rest of the game? No way. Instead I just spammed Creeping Doom/Extended Creeping Doom when I felt like it, which was more for yucks than for its effectiveness (it really did work pretty well on some opponents).
LameSorc was Evocation All Day Long (tm). I had him slamming entire encounters for 290 damage with Thunderbolts and the Grandmaster's Rod + that stupid rod that turns everything to fire damage. Boom! Otherwise he was just there to provide a Smilodon for most of the game, and cast Haste and Improved Invisibility every now and then. Oh, and Mage Armor on the Smilidons, plus sometimes Heroic Invocation. Oh what a sweet spell that is!
Anyway enough of that.
My earlier commentary still obtains, only I must add that real kingdom management somehow manages to be not that much worse than auto. Auto still makes you do a lot of work. Kingdom management itself starves you of "human" resources early on, and then provides you with too much time to do things later in the game. Of course I made things a lot worse in that regard with a mod. When all actions take 1 day, you have hundreds of days to fritter away, but even without that, I can see the late game being almost as boring. There's too much time available before and after Irovetti/Pitax.
As for the House, what can I say? Power creep got extreme through Pitax - Irovetti died like a dog AGAIN, though I killed him even faster this time - only for the devs to be all "oops gotta make the game harder now let's be jackasses". What breaks a lot of power builds in Pathfinder? Stuff that's crit immune, sneak immune, and has really high saves. I know! Let's use lame ghosts. I've totally done that to players in 3.5, but I don't remember ghosts in 3.5 taking half damage from everything . . . or whatever it is those ghosts in Kingmaker have going on. Also my players would do the smart thing and get ghost touch weapons, which are pretty rare in Kingmaker. Yeah I could still roll them most of the time once I got my positioning correct, but damn it was annoying. They just HAD to include the Mage Guards that spam disease at you (albeit with low save DCs). Once I figured out the group composition, I could still use the usual tactics - run off long-term buffs and send FakeValerie straight up the middle. The trick was not overextending with anyone else, and eventually I figured out that FakeValerie could tank entire groups of ghosts on her own with no real help for long enough that she could just melee the Mage Guards to death on her own (that flail that gives -1 AC on hit helped). So that's what I started doing. The ghost encounters were more annoying than deadly. Who likes wasting resources cleaning up Blinding Sickness and Str damage after every encounter? I bought scrolls for it - dozens of them - and had I been less prickly I should have just used those. It was the "last dungeon", right? Right?
Wild hunt encounter design was confusingly bad. I didn't realize that you had to kill the Master before anyone nearby would die - including golems apparently? I had killed the others earlier in the game with Ira cheese, and I don't think those mobs had that capability though I could be wrong. I couldn't get Blind Fight on my pets, so while they had Freedom of Movement, the gaze attacks could still fear them off which was really stupid. They would run into other encounters and other crap. It's classic "they'll roll a 1 eventually!" encounter design. Also sometimes NotNokNok would arbitrarily stop doing much damage to the scouts, and I still can't figure out why. He had Blind Fight so the gaze attacks did nothing to him.
The medusa encounters were "okay" though they would just kill people outright instead of turning them to stone, and again, couldn't give Blind Fight to my pets so whatever. I Ira cheesed the one big Medusa encounter and just bumrushed the rest of them with decent results.
Also, in case anyone needs a way to deal with Mandragora Swarms, it's Fiery Body. Well it's an option anyway. When your Sorcerer can tank swarms better than your Stalwart Defender.
Anyway most of the encounters seemed a). superfluous and b). repetitive. It was a tiresome slog by the end. So I get to Nyrissa, blah blah blah FIGHT and she goes down in one round. I fully buffed out the party, and the damage Bishop Bruiser could do in that state is pretty extreme. Something like +63 damage per hit, and that's without a crit? 3d8 + 63, +53 to hit, 15-20 threat range, 30' reach, and he's scoring attacks of opportunity off every crit NotNokNok and FakeValerie get (and vice versa). Ridiculous! I kind of wish I had been able to sustain that buff level against all the encounters but I don't like resting that much. He only gets 38 rounds of Transformation max, and that's due to a rod.
Nyrissa dies, I execute her, and the Lantern King wrecks my kingdom and curses me. Reload. Nyrissa dies, and I give her the damn cup and tell her to leave me alone, which she does. Problem solved, game over. Did any dev think that I wanted to slog through even more crap, with a curse, just to face the Lantern King? Nope. Bye. Can't say I'm sorry to see Nyrissa become permanently miserable. At least my kingdom is safe. Couldn't really avenge all the other people that Nyrissa murdered throughout the years. Oh well! Too bad, get me out of here kthxbye.
I would have been okay with throwing down with the Lantern King right then and there, since most of my buffs were still running anyway. But all that other crap? I read up on it. No thanks.
