Valley of Dying Things is the first scenario I played in Blades of Avernum, way back when I just had the demo version, and still remains one of my favorites for many reasons.
With most starter adventures, the plot is usually something very light. Recalling my level 1 characters from D&D, for example, I can't tell you how bored I am of standard dungeon crawlers and waves after waves of goblins. VoDT, in this regard, provides a very nice start to your Avernum career. It has a mysterious air about it, and builds up nicely from beginning to middle to end.
VoDT nicely flows from overworld to many areas. There's plenty of side quests to do, and some I've even discovered that I had missed my first time. Routing out small hidden camps is definitely a nice addition to what would normally be a boring overworld map.
The scenario is broken into segments pretty nicely. No one place is too big that you get lost, but areas aren't too small to leave you wanting more. Also, it seems there's always something interesting going on in every map, and always a reason to check every corner.
While VoDT does have these high points, it's not without its flaws, however.
Additionally, some of the fighting got a bit tedious after descending multiple levels. This scenario definitely could've gone with less combat and more intrigue, but it would play out much differently. As it is, it can get dull at a couple points, but it's not unbearable.
For this reason, I can't score it perfectly. All in all, though, it is definitely a welcome departure from the standard story, and one I play regularly just to enjoy it.
Rounded to 4 - GOOD
