I finished GMing Skull and Shackles all the way through last summer and my players had a great time. The first book was rough (it's so dis-empowering), but once it opens up (and boy does it) players in S&S have all the freedom in the world (provided their GM is game).
I did what was posted above: I emphasized the how nasty the officers were and how much the crew began to admire and respect the PCs as things went along. If your GM is game, you have to build relationships with your NPC crew members. This will make the back half the first book well worth it. (Trying to remain spoiler free).
My group also used the ship-to-ship combat as presented in the S&S Player's Guide and they really liked it; by the end of the campaign they were sad that there wasn't more opportunities to use the rules in the campaign because they wanted to do more single ship-on-ship battles rather than the fleet battles at the end of the campaign.
They were so enthusiastic that they coated their ship's ram in Glaucite (the Iron/Adamantine alloy) in preparation for ramming more ships.
With the coming of the new Strange Aeons AP I was wondering, what's your favorite Mythos creature(s) and why?
(Sorry if you've already answered this question)
Hastur is my favorite, because he's so mysterious and thought provoking and creepy, and combines into one entity everything that's compelling and frightening about human nature AND inhuman nature. And the fact that I liked the picture of him in the 1st Edition Deities & Demigods book the best of all the Cthulhu Mythos monster pictures certainly helped!
His complicated real life backstory (Bierce to Chambers to Lovecraft) certainly helps with the enigmatic nature of his being. His exact nature was and is very hard to pin down but I agree that somehow works in his favor to make him seem compelling and strange.
The illustration where he's depicted as a giant tentacled, cilia-covered dinosaur? That's a good one, I wonder which source the artist pulled for that one? Mostly he gets illustrated in the form of the King in Yellow, such as in Bestiary 4. Maybe the kaiju-sized worm/lizard thing was a Derleth interpretation? Idk.
