I'm answering here to this post made by Dj in a different thread:
Did Kevin ever get his other Cthulhu game off the ground, the one where the cultists of different players are trying to awaken their GOO?
I havent played ES, but atm I am loving Elder Sign:Omens, the Dark Pharoah expansion, which I play on my tablet. Do you guys know it?
Never heard anything about the other Kevin's Cthulhu game; in the last month a project about Mythos destroying the world was kickstarted by Sandy Petersen (here). I must say that, even if graphics are cool and the minis rock, I hated the project with all my heart: in order to have any of the stretch goals, you have to load another money in the project, turning the game in a really huge cash cow, without any true reason for this (I understand why The Professor asked for a contribution for his stretch goals, the project raised 14K bucks, but a project collecting 1.4 million dollars? Hey, c'mon...). Additionally, the base game was expensive per se, and I hardly doubt you'll play it that often. But it implemented something similar to what you said: cultists opening gates to summon the Mythos forces.
Elder Sign: Omens is quite a different experience from the tabletop version: the boardgame is much easier, and does not implement any campaign. The expansion, Unseen Forces, fixes somehow the game: first of all, it's huge, you almost double all the decks, granting a great replayability. Additionally, Blessings and Curses make the game vary a lot more, and Master Mythos and new Ancient Ones provide a greater challenge (best game expansion for me in 2013 and maybe in the last three years).
