Oh, definitely, but I don´t know whether I will have a time to play them - I mean, I had my RPG fix and I know that after finishing HotU it will be some time before I touch RPG again.

Knowing which ones are good story modules definitely wouldn´t hurt though.

I definitely would like to try Dance with Rouges and War of Thornes (?) i think it was called?

I have a question: Since you mentioned there were other modules created by BIoware, why they were not part of Diamond Edition as well? Why combine only three of them (where two are not even finished stories), when you could have 3 concluded/separate stories?

This is because Diamond Edition was released in 2005, I believe, and the latter 3 premium modules were released between 2005 and 2006. Another, more complete edition of the game could have been released after that, but never was. What's more, these modules are in a state of legal limbo, so GOG probably had troubles including them as extras with purchase of the Diamond Edition here.

Which is a shame, because this way most people who play NWN don't even know that there is some official content they missed.

So that´s why...
Interesting that they were still creating new modules, even so many years after release of the game AND NWN2 being released (which seems to be more compliant with 3.5 rules).

From those original, that you described, I would be interested only in Wyvern Crown of Cormyr - please, tell me that at least this story is finished....

And what about those recommended modules you mentioned? Can you tell me about them, please?

Sorry, my bad - I said the latter premium modules were released between 2005-2008, whereas I meant 2005-2006. I think the last of them, Wyvern Crown of Cormyr, was released about the time NWN2 showed up, not sure if slightly before or slightly after its premiere.

The good news is that the latter three modules are all finished stories, including Wyvern Crown of Cormyr. :)
They're longer, too. Quite ironically, the premium modules included in the Diamond Edition are pretty clearly inferior to the ones that most people don't even know about.

Regarding Wyvern Crown of Cormyr specifically, I said that its story is "enjoyable, but not fantastic". To expand on this, I'd like to say that WCoC's story is actually very good for the most part, but unfortunately its ending is rushed and somewhat anticlimatic. It's still a complete story, that's for sure, but DLA (developers behind Wyvern Crown of Cormyr) could have finished it off in a better way.

Nevertheless, that's still my favorite premium module. :) Make sure to keep several save files, though, because I once found myself stuck due to some bug and if it wasn't for an older save file I had, I would probably be unable to carry on. Don't know if this bug is frequent or not, but better be safe than sorry. Melee classes fit WCoC better than casters thematically, but I don't think there'd be any problem playing a wizard or a druid. I like playing WCoC as a paladin, because this gives me access to the Summon Mount feat, so I don't have to buy a horse. :P

Now, regarding unofficial modules, I can't recommend the "Prophet" campaign enough. It's a 40-hour long adventure made out of four modules. Many people who played it compared its quality to Planescape Torment. Its storyline is original, it's multiplayer-compatible if that's of any value to you (but fully playable solo as well) and the ending is mindblowing. It is, however, very linear - there are few side quests, but I think that helps you focus on the story. Another possible "issue" is that it's mainly designed for good-aligned characters, so you wouldn't get a lot of evil choices to make if that's your cup of tea. It is, however, the best story-driven RPG I've played.

Other suggestions:
-Honor among Thieves - for rogues only, made by the guy behind the "Prophet' campaign and set in the same world
-Cave of Songs - another module made by the same guy, it's only a few hours long, but it's still very good
-Almraiven - for wizards or sorcerers only, haven't yet played it but heard it's truly marvelous (it's actually the first part of a trilogy)
-Swordflight - a campaign still in the making, the first three chapters are released and playable at the moment, it's known for both its high quality and its high difficulty

And even more ideas:
-A Hunt Through The Dark (a campaign for drows only)
-Aielund Saga (VERY lengthy, but very good)
-Snow Hunt (a module for one evening)
-Elegia Eternum (high quality, even features voice-acting)

I could go on and on, because there is a whole sea of great content for NWN. It would take years to play through everything of quality. ;)

Nah, thank you, this is more than enough ;)
Never heard about the "Prophet" campaign, but I will definitely check it out and majoirty of the other mentioned as well :)

I know what you mean, I am an avid Thief player, and there is plethora of fan made missions, some of them, dare I say it, better if not good as the original games :)

The Prophet series is my favorite. Though it may not be for everyone. It is more story oriented and less combat oriented, but that is how I like it.

I played Cave of Songs, Honor Among Thieves, and Prophet as a series for one character.

shadow guard sequel has been cancelled...

I felt the same way about this module in particular...kinda the issue with the Kingmaker modules in general. Kingmaker itself felt like it was mostly complete, although I was annoyed that it rushed me to the conclusion, but Shadowguard felt like it was just starting to get good when it ended. Definitely seemed like there was a lot more story to tell with that one. I never finished Witch's Wake--I think my controls glitched out when I started it and the camera was really obnoxious and wonky, so I didn't have the patience to finish something that I was aware was going to be incomplete. Plus, as others have said, there are so many fan-made modules out there that I'd rather sink my teeth into. :)
