Here’s a board game not for the faint of heart. Loosely based on the works of H.P. Lovecraft (especially The Call of Cthulhu), Arkham Horror from Fantasy Flight is one of the most elaborate games you can find. Play time is typically four to five hours. Each player chooses an investigator, and as they explore the town of Arkham, the board gradually manifests various obstacles and monsters bent on annihilating the universe.
