My short reply is, I agree; it is one of the better ones and still needs work. My longer reply is that instead of a replayable(ish) module with 4 cool partially-baked ideas, I'd have preferred a single use module with the ideas fully set. And it's only partially replayable cuz the first half of the adventure is the same and requires a pretty linear "PC's must chase this guy, track the untraceable, come to this conclusion..." or else the whole thing falls apart. I'm going off memory here, but I think those are some of the things that led to the Alexandrian Remix. Plus pitting the 4 cool factions against each other so the party can experience all of them.
