I tried Runes of Blood.
I gave up after about 6 hours, it seems very large & too many puzzles for me.
I find it odd that someone would spend months making a mod, & not bother to spend a couple of days writing a walkthrough.

Edit:
Well I slogged through all the puzzles till almost the end of the mod, but I couldn't finish it because it must be bugged.
I can't get the gate open to enter Belworth.
According to the FAQ you should be able to "bum rush the solders" I killed everything in the area & nobody had a key to the gate, & you can't pick it or bash it.
It was a boring mod, but I would have liked to finish it after putting so much time into it.

Edit: 2
I got it finished, turns out you don't need to get that gate open anyway.
The worst thing, is I tried this mod because it was on the list of "Romance Mods" (Solienne (female elf ranger) for males and females.)
I had Solienne from the start & never dropped her or allowed her to be killed & not only was there no romance options,
after I hired her she never spoke at all, other than to ask for more money on level ups, & occasionally tell me it was safe to rest here.

I have played through Citadel. I don't see it get lots of mention, but it's worth a look. I ended up playing through it twice.

The good parts about it are that it has a good story behind it, the world is detailed and unique, and it has epic scope (levels 6-32). It is a huge module with far more than the 60 hours of gameplay advertised.

It is high magic, and in almost every combat, you are outnumbered by opponents with a challenge rating of Impossible. The module throws at you every possible combination of annoying and abusive powers and tactics. So you must in respond in kind with your own combination of abusive powers and tactics.

The tactical challenge is good, and I like that part. The downside is that you rely far more heavily on magical equipment to survive than you do on your character's abilities. (Keep in mind when you are creating a character, that a large percentage of the time you will be facing opponents who have 5+ levels on you.)

One of the other annoyances is that the Journal entries are not always clear as to what you need to do next (though the walkthrough sufficiently covers things if you get stuck). There are so many intersecting storylines running at once that it is a challenge to keep track of them all. (Though if you do not like linear modules, Citadel is about as non-linear as it gets.)

There are also no autosaves (and that's annoying the first time you play a while without saving and look back for autosave). But you'll get into the habit of frequently saving the game.

The first time I played it I got frustrated and quit. I gave it another shot, and I'm glad I did.

For NWN 2, I will vouch for:

Maimed God Saga. Really great stuff - great NPC's, good suspense, the journeys actually feel like actual long journeys with events rather than just showing up at your location.

Harp & Chrysanthemum. Great story and very polished.

NWN 1

Dance with Rogues is better than any of the original content and expansions put out by bioware IMO. Absolutely great if you're okay with 'R' rated material.

For anyone wondering, [url=http://nwvault.ign.com/View.php?view=Modules.Detail&id=6375 ]here[/url]'s the link.

I haven't played NWN in a while, so I only just found out the old Vault is gone. :(

Fortunately, it seems everything is moving to the new Vault, and all but one of the modules I recommended are already available for download there, so I updated the links in my posts accordingly. I encourage everyone to do the same! :)

Here's the link to the new Vault:
http://neverwintervault.org/

I wholeheartedly recommend the snowy adventure "Heart of Winter", downloadable from Neverwinter Vault.

Prepared by an experienced NWN module builder Glenn Pudney, the module is a nice, short story (around 6-10 hours depending how you play it) set in an believable icy landscape: you can expect a village in the woods, caverns, barbarian camp as well as snowy no-mans-land and cemeteries. Interestingly, locations and storyline are based roughly on Icewind Dale's addon Heart of Winter... You can in fact use the original ID: HoW walkthrough if you want to peer into quests and their outcomes! This fact, together with the really well painted locations (I attach some screens) make you think you are in fact playing an "official" module.

The recommended level is around 20, but I found it personally a bit too easy on this level with my 21 lev Sorcerer/RDD/CoT build. Also, the henchwoman is a waste of time: she's a good fighter, but she does not add anything to the storyline.

I recommend Rogueknight333's Swordflight series (two parts so far completed of a possible five in total).

For an introduction you can read about my impressions here:
<span class="bold">Swordflight Series - Part I</span>
<span class="bold">Swordflight Series - Part II</span>

I also recommend Savant's Aielund Saga, recently having completed a detailed thirty-four-part recounting of my epic run with a Paladin character, starting at first level and reaching thirty-sixth - a godly Champion of Torm (20) / Paladin (12) / Fighter (4). The first post:
<span class="bold">The Aielund Saga: Act One - Part I</span>

As a demanding player who spent many long hours in NWN world (and quitted --- this is too addictive!), I have these recommendations in order to make you experience NWN to the fullest. Original Campaign is weak, Hordes of Underdark is very nice to play (but limited to underground areas), Shadows of Undrentide is playable (especially very nice snowy beginning). Yet all these do not feel “realistic” in terms of proper RPG experience. As a person in his 30s I considered them… childish? However, there are two modules I recommend ex aequo and without reservations:

/1A/
-- AIELUND SAGA – absolutely epic, long gameplay (Lilura who posted her message above wrote a very nice walkthrough). You can scrap original campaign and just go straight to the Saga, downloading all the modules and required custom content from the NWN Vault. Stephen L. Nowland, the author devoted around 6-7 years of passionate scripting and imaginative writing to make the Saga, which currently has its own overseer, Balkoth, who constantly improves its performance. Aielund Saga is THE BEST NWN story up to day (2015) in terms of (a) epic scope of gameplay experience and (b) utilization of immersive custom content. This content makes you walk through snowy wastelands, burned-out forests, blossoming farmlands, soaking rainy villages, dvarwen cities, dense elven forests, windy deserts (indeed, Aielund offers lots of lovely open-sky-areas!). You can wreak havoc in a gentlemen’s club, hire a helping hand of a dragon, travel with an elderly noble paladin, forgive your former enemies to befriend them and participate in court intrigues. Henchmen have their unique personality and a few romance options are available adding the spice (Robert for women, Criosa for men, starting from act III). There is also a feeling of familiarity as you visit the same places again after, not to mention horse riding that adds a realistic touch.

/1B/
-- DANCE WITH ROGUES– must-play, difficult, long, amazing module made for thieves (e.g. you get experience for picking locks and little experience for killing), made with insight and passion. It took YEARS of daydreaming and hard work by the authoress (Valine) and it has its own WIKIA walkthrough which in itself says something about its popularity. THE BEST up to 2015 in terms of (a) RPG feel (b) realism and (c) psychological depth of interaction with henchmen and romance options. You are a fragile women and sometimes you can only choose between running/being raped/dying. You are almost always poor and have to make moral choices (e.g. entering a romance with a wealthy man, or maybe making traps and selling them?) to improve your situation. The story has lots of sexual content, though, both verbal and graphical thus it is not recommended for children. Yet in terms of roleplaying it is absolutely stunning, and romances are not superficial, but have important consequences. If you wonder how a pretty, abused former princess would feel in a paternalistic and sexually-suppressed culture, then you must play this. Also, the gameplay can have impact on your mind. It’s not a joke: the experience might strengthen your empathy towards women (especially if you are male). And the finale with party lost in the endless desert with menacing tombstones as well as an undercover visit in the orc camp give you thrills. You will be never safe, but after all that it is to be done, you can have your own barony!
_____

So these two offer a pinnacle of NWN experience. If you have more time, other recommendations would include:


/2/ Shadowlords/DREAMCATCHER/Demon - with Dreamcatcher probably being the best of them. Adam Miller, the author made memorable modules with an innovative approach to terrain forming (mountains made without tiles!, savannah etc.) and scripting (you can fly on the back of a dragon and lead a platoon of elves).

/3/ Wyvern Crown of Cormyr – it is now freely obtainable from the web, but requires internet connection (as a former premium module) every time you load it. Very „medieval” in terms of experience of low-magic world. It introduces horses and allows for jousting and participating in fighting tournaments.

/4/Darkness over Daggerford – nicely made, the game is not plot-central and feels more like a collection of interesting sub-quests for an adventurer. A very pleasing design of outdoor areas and nice music. Also, there is a world map available and you can have your own stronghold that can be arranged to your liking (carpets, furniture etc) which brings memories of Baldur’s Gate 2.

I have also heard good things about The Wanderer, which seemingly consumed many years of the authors' life. I did not play it, but you can read the review a few posts above)

Well apart from 1/ Dance with Rogues and 2/ Aielund Saga (see my post above) there is my new all times favourite...

3/ --- BASTARD OF KOSIGAN - a dashing medieval adventure with historical chunks thrown in - a feast for anyone interested in medieval court intrigues (there are 5 modules originally in French, and they were translated to English - 4 of them are available in the new Vault http://neverwintervault.org and I managed to filch the 5th translation from the author himself!). It is a genuine novel-like story, in terms of the plot and court intrigue THE BEST to date. There is an actual novel written by the author (in French) as well. The next volumes are underway, with the last one that will contain the final installment of the story (with the protagonist going to Rome and Vatican).

The game takes place in a medieval setting where Inquisition roams the lands and magic, although existent, is disappearing due to the spread of Christiniaty. What a nice idea to mix fantasy with history... You are a Bastard of Kosigan, a bastard son of a ruler of Kosigan, which is a vassal county of Burgundy that announced independence from France. You will soon realize that something weird is happening and that the plot related to the lineage to the throne of Kosigan is underway. French want to intervene, other claimants emerge, and strangely all of them are prone to using both diplomatic and criminal means. Quite obvious considering the fact the stakes are high! Characters of the story are well built (with deformed guard Slynt and seductive Belle being ma favourites) and the writing is suggestive and concise at the same time, which is a rare feat indeed among the writers. Twists of the plot and moral choices are abundant, as well as - let's say - an entertaining French approach to eroticism. There is also a VERY immersive choice of custom music. If this does not convince you, then know that the author Faben Cerutti is a writer and historian, well versed in medieval sociology, who spent 7 years in preparing the mods. If you ever watched "Game of thrones" or related movie and thought "I would do things differently" then play Bastard, as contrary to what you experience in a regular book or a movie, you can have a choice.

PS. There is some problem with installation of 5th module in English (hint: you should place BOTH kosigan_english.tlk and kosigan.tlk in the TLK folder). Also the 2nd module has problem with loading saves (sometimes it is every 5-6th try that the game manages to load without crashing NWN. But it is still worth it!

Hope these reviews help.

Added this to the op as well, but most of the modules are at http://neverwintervault.org/

Aha! Ok, looking for things there is hard... Thanks though.
