Lords of Waterdeep was awesome, and Scoundrels of Skullport makes it even bigger, better, and crazier, like the original game on steroids. You get two expansions in one: Undermountain and Skullport. Both feature 3 new Lord cards, 3 new basic building locations (each on a separate small game board), a ton of new buyable buildings, plus a huge amount of new quest and intrigue cards. Skullport includes a Corruption mechanic that penalizes your end-game points by the number of Corruption tokens (blue skulls) you have vs. how many remain on the included Corruption Track (also on a small game board). You gain Corruption by using the awesome new buildings or completing some of the crazy new quests. Corruption is easy to gain but hard to get rid of (ask any politician, lol), but the game includes a number of ways to get rid of it a bit at a time (such as through using certain buildings, completing certain quests, or playing certain intrigue cards). Corruption management is vital. Don't worry about it early, but be sure to start cutting back by mid-game and reversing the number whenever possible.
