"In Eldritch Horror, one to eight players take the roles of globetrotting investigators, who must work together to solve mysteries related to an Ancient One – an elder being intent on global destruction. Along the way, you’ll gather clues, encounter strange and mysterious circumstances, battle monsters, and embark on daring expeditions."
"Each loathsome Ancient One is shrouded in secrecy, and each comes with a unique deck of Mystery cards, which draws you and your group of investigators ever deeper into the narrative. The tasks on these Mystery cards, along with the locations of otherworldly gates, menacing monsters, and helpful clues will inform both your travel plans and the dangers you confront.
Each Mystery card presents a new objective to complete, and each mystery you solve will bring you one step nearer to preventing the destruction of our world. With clues scattered across the globe, you’ll find adventure no matter where you travel. Maybe you’ll need to explore the vast expanse of Tunguska to research a strange comet, which seems to coincide with the rumblings of ancient evil. Perhaps, you’ll be tasked with discovering what lies behind the veil between our world and other, strange, dimensions.
Only by solving mysteries specific to the Ancient One you face will you and your fellow investigators be able to prevent impending doom."
The game comes with 12 different investigators to choose from, and a ton of cards, so FF is promising no two games with be the same.
Personally, I think we need more Cthulhu games like we need a hole in the head. But Fantasy Flight will have demos running at GenCon. So check it out if you're going, and let us know how it is!
