This is why I need to clean up more often:
I completed the first NWN expansion, Shadows of Undrentide, today. I was expecting it to be longer than it actually was (20+ hours according to the manual) but I can’t complain much.
How does SoU compare to the others? I think HotU>SoU>NWN sums it up nicely.
I was keen on trying out the Prestige Classes introduced in this expansion and gave the Shadowdancer a try for my first campaign run. I was a Rogue 7/Shadowdancer 6 at the end of the game and I found the Rogue’s abilities much more useful than the Shadowdancer’s. The Hide in Plain Sight feat, which the Shadowdancer gains at the first level, does lend itself well to the kind of hit and run tactics the Rogue specialises in but I didn’t find the Shadowdancer feats gained at higher levels particularly useful. I ended up relying heavily on the Rogue’s stealth attack ability and this meant I was often in trouble when faced with opponents who weren’t susceptible to that. Fortunately, my henchman of choice, a dwarven Rogue 4/Cleric 9, proved to be quite helpful in those situations.
Technically, the game ran fine with the exception of one area in Chapter 2’s Crypt Tower. The area in question is quite large and featured a maze with walls that would randomly disappear and reappear. It was an interesting design but it was so resource-heavy the game almost became unplayable.
