Three stars, not perfect, but pretty good. It dropped a star on the player side because the party had been getting big "desert wastes" vibe from the campaign, and the switch to a city and diplomacy based scenario didn't fit with the playing style so far. I knocked off another star for the GM perspective, because if the players blow off the intrigue, and negotiations in Katapesh, there really isn't much substance here until the raid on the "one source".
I liked it however, worth playing, just not as good as the previous two, nor as good as the follow on (End of Eternity)
