Core Listing & Comments

Be sure to check out the comments section, too.

Aielund Saga, by Savant.
Doesn't need an introduction, does it? This is flagship. My coverage.
Almraiven & Shadewood, by Fester Pot.
Polished, unique, and beautifully presented. Fester Pot is about details. This is a proper low-level Wizard campaign with a laboratory and everything that goes with it. Will be known as The Auren Trilogy once the third installment is released.
Aribeth's Redemption, by Daniel Muth.
I've read positive comments about this over the years.
Bastard of Kosigan, by Fabien Cerutti.
Mythic-medieval setting. Great writing and characterizations; some of the very best. The finale is one of the best set pieces I've seen, too. First part covered by me here. It's a pity Fabien has no interest in fixing the bugs that plague the English version (he's moved on as a novelist now, which is fair enough).
• Blackguard, by Steve B.
This one has always been popular and highly regarded. I've heard its combat is tough, too.

I would suggest a Trilogy called Blackguard. Is one of the best written stories in NWN. It does tend to start slowly in the first module but it picks up in second and the third. You play as an evil character on the path to become a Blackguard (quite similar to Path of Evil module from NWN2) and towards the end of module 3 you even encounter and fight heroes like Drizzt or Deekin. - Redrake.

I found the writing to be childish and nowhere near the level of some other modules, but perhaps it gets better as the campaign wears on?
• Bone Kenning I: Art of the Thanaturge, by Wes Lewis
Reviewed by me here.
Breach, by Akkei.
Another evil-only module, The Breach is authored by Akkei who is best known for his Orcs series: Awakening of Arak-Hur and Return to Al-Dha (see below). In Breach chargen, you choose between four custom undead lords and then recruit a party from the Undead Nation to wreak havoc on divine beings and mundane races. The lords are clvl25 and consist of Risen, Mummy, Vamp and Shadow corresponding to warrior, priest, rogue and sorc. They have special feats that allow them to absorb souls, inflict pestilence and plague, and appear as poltergeists in order to communicate with humans and other mundanes. You don't get experience points, you trade souls for upgrades. You don't rest, you sap souls. You don't die, you lose collected souls. To my dismay, there are cutscene bugs introduced by subsequent official patches.
Caereena - Krakona Rising, by Dallo, Skyrmir, RyanDarth & gaoneng
Hack-and-slash module with poorly designed hack-and-slash is meh. Not terrible, but...yeah. Low priority to play. - Balkoth.

And yet others have really enjoyed it? Incidentally, Balkoth's modules are non-standard hack n slash but very well put together. They are: A Peremptory Summons and Siege of the Heavens.

Cave of Songs, Honor Among Thieves & Prophet, by Baldecaran.
The first two are top 10 all-time. I can play CoS and HAT before the Prophet series and use the same character if you like. CoS is a wonderful adventure and early masterpiece that eases new players into NWN and the Runelands custom campaign setting, and HAT is the best rogue-based module on the NWN platform.

Claw Chronicles (CC1: Gates of Myth Drannor & CC2: Sorrow of Faerûn), by Abaddon.
I remember Abaddon for his two traditional Forgotten Realms modules, Gates of Myth Drannor and Sorrow of Faerûn. CC3 was never released. I hit a showstopper bug several hours into CC1 and spent hours looking for a workaround, after which I rage-uninstalled. To that point, I was enjoying his area design - especially the thickly layered ambient sounds in his forests, and use of lighting. Only two other things I recall: 1. mundane builds need +1 weapons ASAP due to soak 2. there are rest restrictions but not as strict as Aielund/CToT.
Cormyrean Nights, by Servilan.
Reviewed by me here. Great for newbies.
Darkness Over Daggerford, by Ossian Studios.
Another good starting-point for newbies, though it's much longer than Cormyrean Nights and Cave of Songs. You will have to dig in to complete it. My intro here
Elegia Eternum & Excrucio Eternum by Stefan Gagne.
I recommend them to you because they are my favourites and have a good replayability. - Lanjane.
HeavensGate, by Brad W. Bartram
A new entry that has been well-received, though I was put off by some of the combat encounter design which didn't seem all that well thought-out. Has a sort of Legend of Zelda flavor to it, with some nice touches.
Hex Coda, by Stefan Gagne.
The Hex Coda is an absolutely amazing module and the Eternum series is also really, really good. The catch is that they're both by Stefan Gagne who is amazing at writing and characters but doesn't know jack about combat in NWN (and freely admits it). So the modules basically have combat as a formality -- it happens where you'd expect but it's basically faceroll and assumes you'll handily win. Could beat it as a strength based wizard. - Balkoth.

This is pretty much my experience, too. The combat is such a drag but the module is still easily top 10 all-time due to its writing, characterizations, role-playing opportunities and general inventiveness in regard to tech mechanics.
Hunt Through the Dark, by Markus Schlegel. Six-part Drow series.
Lankhmar Nights, by Udasu. [*]
Esteemed by members of the community; its assets recently got updated with Project Q, too.
Lords of Darkness, by Fantus.
Lords of Darkness just has shittons (that's a new unit of measurement) of just killing the same mobs over and over and over and over again during combat segments. - Balkoth.

Balkoth, ever the salesman. :P

Lord of Terror, by Tolitz Rosel
I'm a little conflicted with this one... it doesn't really play like the original Diablo, the loot system for which is a masterpiece. No random dungeons, either - those two things are the soul of Diablo and what makes it so addictive and replayable. It does manage to capture some atmosphere, but that's just because of the ripped assets. Still, tons of work has gone into it.
Orcs, by Akkei
Evil-only. Non-linear exploration. Translation is only passable. Starting-point write-up here.
Paladin: Twilight & Midnight, by Rick Burton.
This is a difficult, oldskool module made in the early days. I gave up because I was having compatibility issues with NWN at the time. That said, can't ignore this.
Penultima, by Stefan Gagne.
The Penultima series (and subsequent Penultima Rerolled) are Stefan's earlier works and are reasonably good (getting better as you go through the two series, shockingly enough)...but Eternum and Hex Coda are definitely better. Combat is still pretty faceroll and not really interesting. - Balkoth.
Rose of Eternity, by Challseus.
Comparable to Baldecaran's Prophet.
Saleron's Gambit, by Tiberius209.
Highly regarded BG-esque campaign.
Sanctum of the Archmage, by Andarian.
Haven't completed this as yet but it's a labor of love that pushes the Aurora engine to its limits.

Sanctum of the Archmage: The Sight was very good and fairly difficult combat, I'd probably rate it third in terms of combat modules (behind Aielund and Swordflight)...but it's really heavily story focused (which isn't a bad thing, of course). Kind of funny how the best three campaigns for combat also have really good story.  - Balkoth. See also comment by Andarian.
Sands of Fate, by John McA
One of the few modules that will take you all the way to 40th level. This is for post-HotU characters.
Shadowlords, Dreamcatcher & Demon by Adam Miller.
I only would add to list the Shadowlords, Dreamcatcher, and Demon trilogy made by Adam Miller, they are not perfect but I think they deserve more love. I especially liked the war part in Dreamcatcher (Shadowlords was a bit rough, but this was due to the inexperience of the author, that later improved really a lot). - Marco Santaro.
Siege of Shadowdale, Crimson Tides of Tethyr & Tyrants of the Moonsea, by Alazander.
Covered by me here, here and here. CToT is a top 5 all-time epic campaign, no question.
Snickersnack! by nereng.
Cute and funny module with innovative features such as obscured maps (fog of war in the maze returns when out of range) and text entry system for user input of passcodes (something you almost never see in RPGs that are not fully text-based).
Snow Hunt, by Rogueknight 333.
My coverage here.
Swordflight Series, by Rogueknight333.
I think this is the most-voted-for series on the New Vault, hovering around the 90% mark. Review by me here.
Tales of Arterra, by Kevin Chan.
Tales of Arterra is another highly regarded NWN module series that was heavily influenced by Baldur's Gate. - Rogueknight 333.
Tortured Hearts, by SubBassman.
Another Hall of Fame module that I'd like to get around to playing. Held in high esteem by the community.
