Bought NWN EE for the "new" premium modules, soundtracks, and promises of things to come, ran a quick test and got sucked into the game again, playing two of the old premium modules in order to get a character to level 5. Both had good sides to them but ended up being rather disappointing. They also made me remember the good sides of NWN (the creativity, the imagination, how much can be achieved with so little - graphics really don't matter that much, you get drawn in regardless) as well as the bad ones (awkward pathfinding, the incredibly long pauses during combat that almost make the PC seem unresponsive to commands, etc.).

Witch's Wake (from lvl 1 to lvl 3)

This one was a replay; I still remembered two things about it: that I liked it, and that it was unfinished, more like a first chapter to a series that never happened.

+ The story-telling is good, it has a slightly poetic, mysterious quality to it, quite reminiscent of Planescape: Torment, and it actually adopts some of its elements (some might say "rips off", but I liked it).
+ XP are rewarded for "roleplaying your character", advancing the story, finding secrets or learning something new
+/- few XP are rewarded for combat and opponents often respawn, so hack and slash with a high body count is discouraged, you're better off running from or sneaking around enemies, and that makes more sense than killing everything that moves; but completely avoiding them isn't always possible either, and as a result, the combat in this module becomes even more tedious and annoying than usual
+/- resting is nerfed, you only regain ~ 2 HP per level when resting and have to wait 3 minutes before you're able to rest again, and healing resources are a bit rare as well. I guess it encourages caution, but it's also a bit lame, having to find a safe resting spot and then wait for several seconds only to regain a few measly HP
+/- just one voiceactress doing all the narration and voices, including male ones; but I liked her
- the ending is very abrupt, even more so than I remembered, and it's pretty clear that this was not how the story was meant to end

Shadowguard (first time, from lvl 3 to lvl 5)

+ it starts with a prologue spoken by a first person narrator and it actually adapts to your PC's gender; there's a male voice for male characters and a female voice for female characters (I prefered the latter)
+ in the beginning you get a lore book that actually features cutscenes and voiceovers if you read it (like re-enacted history - a nice touch and a creative use of the engine)
- not that you *have* to read them, but the regular lorebooks are too long and ultimately pointless, the one described above would have sufficed
+/- resting is only possible if you have rations; but since regular rations only cost 1 gp and you're pretty rich in this modules, this system is rather pointless and easily ignored
+ the story-telling, while conventional, works fine, and the quest system as well; they entertained me enough for me to keep going
- the story itself turns out to be less ambivalent and interesting than the beginning would have you think, it becomes a pretty simple and therefor predictable matter of black and white to the point of appearing totally naive, and that's a pity because the beginning clearly suggested that there was some awareness that things aren't always as clear cut. who knows, maybe they still had some twists planned, further down the storyline ...
- ... but even though this module is considerably longer than Witch's Wake, it ends without concluding the story arc as well
- and even worse, I ran into several bugs at the end, one of them gamebreaking, so I had to watch the last two minutes or so on YouTube, since in my playthrough, the concluding conversation was not triggered

So in the end, while both modules have a few nice qualities, I can't really recommend them to anyone but the most hardcore NWN fans. It was interesting to see what they're like and while playing I was invested in them, but that just increases the disappointment about their rushed endings. The time needed to play through these unfinished and in hindsight forgettable stories could be invested in playing more satisfying community modules.
