Expedition to the Ruined Partial Maps of Undermountain with a Really Dumb Backstory? There must be a fault in the poll.
That aside, the adventures were rather a mixed bag for me. The adventure path started brilliantly with
Sunless Citadel and
Forge of Fury but, with the exception of
Speaker in Dreams, the rest were mediocre to appalling, IMO. I like the Barrow/Sinister Spire/Fortress trilogy that finished off 3.5E; ditto for FR's Cormyr/Shadowdale/Anauroch trilogy (which I will shortly be trying to convert to Savage Worlds).
I'm still amazed both by how good and how useful the environmental series books were.
Cityscape and
Dungeonscape, not so much, but the terrain ones were excellent.
I'm a big FR fan but
City of the Spider Queen, for me, is an almost perfect example of bad adventure design. I just realised: like
Undermountain, the maps for this were wrong too! I think WotC should learn at least two lessons from this product:
1. never take four years to tell the backstory of one of your modules in six novels; and
2. a big adventure needs at least one place for R&R and buying and selling.
However, look at
Red Hand of Doom. That's a masterpiece and
Ravenloft was a terrific update.
What a shame we didn't see more adventures from WotC before the dying days of 3.5E.
