Played this at a local game day yesterday with my Investigator (Empiricist), who is a skill monkey machine. I had no idea what i was getting into, and it was a blast. It's nice to see the Intrigue Rules get play, it's giving me ideas for the home game.
There were five of us at the table, and between myself and a Bard, we pretty much learned everything there was to learn, though we had huge problems with the fights (our three combat characters couldn't make a save, or not take damage). With no cleric, we had multiple characters drop over the course of the game.
Thankfully, when we targetted the big bad at the oasis and took her down (with one down unconscious, and the other in the negatives), we were able to trigger the end of the encounter, and still save the docs.
I totally enjoyed it, I'd be happy to run it someday.
