Some minor spoilers for Dungeon adventures
Well, a gadzillion of them, really. It depends on what you are looking for.
I like the Necromancer Game products for their flexibility. They are strong site-based adventures. There have been a number of good political / urban adventures in Dungeon Magazine in the past couple of years. Goodman Games modules have a good reputation, although I haven't purchased any of theirs.
Mad God's Key and Thirds of Purloined Vellum from Dungeon Magazine are, I find, excellent starting adventures that can have a good political aspect to them. The next time I start a campaign I am probably going to run...
Mad God's Key
Thirds of Purloined Vellum
(Serial Killer vs. Minor Nobles)
(Giant Bees vs. Halfling Village)
(Necromancers Wanting Serial Killer's Body)
...for the first five adventures. Sorry, I don't remember the names of all of the adventures. Adventures 1, 3 and 5 will be tied into the same sub-plot, although they are not intended to run together. Now, all of these are from Dungeon Magazine. It is a great value and there is usually something I can use or adapt from each adventure. It is a rare month where I can use little or nothing. And, I run exclusively my homebrew so I'm constantly tinkering.
I'm currently running a saga where I am heavily using the Age of Worms adventures with the worms stripped out. I used the first three adventures in the theme of the adventures stopping a demon-worshipping cult. Then I used the adventure where the party retrieves a fallen friend for the illithid tie-in. Which leads us back to the Age of Worms and the Hall of Harsh Reflections and the gladatorial adventure after that. Them, I'm going with homebrew stuff about the conflict between the illithids and the yuan-ti with the players in the middle.
So, I can't really tell you specific items that are good and have the reccommendation be meaningful. What kind of campaign do you want to run?
