First off, I buyed this book when it was discounted.
Allright i'm using this module for my players and loved the concept beyound it, a long jourmey that will test everyone.
Evertinthing starts pretty casual and realistic, going full Lovercraft onece beyound the mountain.
The book id pretty big, but it would have been shrinked a bit.
I like the reference to real event, but i had no use (and no way i would my player) to put on with all the tecnically of charging boat, planes and similar things that will slow the game.
There is an impressive roster of pnc and the story is pretty reilroading. There is a tight shedulesof events.
Plot and gimmicks are passables, i don't know your players but HERE is the really drawback for the Keepers.
You will have to muscle up and shreds, remove and add on things that will manage to make the adventure enjoyable.
-I lollend reading the NPC and the overall plot
-At first is normal but when you will see more and more the Mythos
-A clear Timline and lots of notes
-A long campain
-They have updated with the INDEX on the pdf
-You have to work to make the coiche the player make be revelant.
-THAT CHOICE should be in the last chapter!
-More than one chapter have event that can end the adventure, one even before you sail from new York.
-Important event that are scripted
-A lot of Fluf that you will not show to the player, has the infinity inventory check list, statistic for boats and planes et ecc..
Buy it on a sale, the modules is great but the price is too high for a previtten adventure that the keepers has to work the plyer feel they're choice are revelant.
This said, after an heavily GM tweaking, i had a blast with my group in this adventure.
The elder things show no one time signs tha they could collaborate, respect or at least shold came to term with the humans for the survival of evreyone (they thinks in alien way ok, but at the same time they are intelligent and not suicidal)...
Then why for the love of Chtullu they had buried Gendy like one of them, the modules even say that this should made the PG think about it bat is never mentioned again or used in any way or at least justified.
More then one PG has to die or game over this as frustrated me more.
UPDATE: They have put an index in the PDF
