I have the Arkham Horror Boardgame with two expansions. It was created by very knowledgable genre fans with tons of ideas and information regarding the locals, monsters, and everything else.
It is just a bit too heavy on game mechanics and has so many icon and counters it's easy to lose track of something going on. It doe a decent job creating a hopeless and dreadful feeling as you are constantly aware of one of the Old Ones sitting on the table about to be unleashed.
This on the otherhand this Innsmouth game looks a bit on the simple side. Dunno. Would like to playtest it though.
