Arkham Horror: The Board Game

0See it at Amazon!
MSRP: $65.95 USD
Players: 1-6
Playtime: 2-3 hours
Ages: 14+
Arkham Horror is a cooperative board game where teams of players work together to combat various terrors. Embark on a journey through Arkham as one of six investigators, solving mysteries and defeating horrific beasts. With multiple campaigns to explore and a significant luck component, the game is highly replayable. However, it's not an easy game; it requires time to set up and teach, and gameplay can extend over multiple hours. My first attempt with friends on the easiest campaign was disastrous, and solo play proved challenging as well. The thrill of completing that first winning game is truly rewarding.
Arkham Horror: The Board Game Expansions
There are three expansions for the Arkham Horror board game, each adding new depth to the base game.

The Dead of Night is a smaller expansion with a corresponding price point. It adds two new scenarios and four new investigators, enhancing your adventures in the eerie darkness.
Other Arkham Horror Board Games
Several other board games exist within the Arkham Horror universe, each offering standalone adventures without requiring the base game. These titles, featuring familiar characters, come with their own expansions.
Elder Sign

MSRP: $39.99 USD
Players: 1-8
Playtime: 1-2 hours
Ages: 14+
Elder Sign, one of the earliest games in the Arkham Files franchise, is a dice-rolling board game suitable for one to eight players. It's the most accessible game in the series, driven primarily by dice rolls. Players roll dice based on their investigator's stats to fight monsters, find clues, and solve mysteries before time runs out.

Elder Sign has six expansions: Unseen Forces, Gates of Arkham, Omens of Ice, Grave Consequences, Omens of the Deep, and Omens of the Pharaoh. Grave Consequences is a standalone deck and can be played with or without the core game. The last expansion was released in 2018, and it's uncertain if more will follow.
Mansions of Madness (2nd Edition)

0See it at Amazon!
MSRP: $109.95 USD
Players: 1-5
Playtime: 2-3 hours
Ages: 14+
Mansions of Madness is an app-driven dungeon crawler set in the same universe as Eldritch Horror and Elder Sign. It supports one to five players and uses an app to guide the narrative, setup, and gameplay. The combination of tactical gameplay and app integration is particularly engaging, and the app allows you to pause and resume games, though you'll need to set up the physical pieces again.
Mansions of Madness Expansions
There are two expansions for Mansions of Madness, both cooperative and app-guided.

MSRP: $69.99 USD

MSRP: $39.19 USD
Players: 1-5
Playtime: 2-3 hours
Ages: 14+
This more affordable expansion introduces two new investigators, two new scenarios, and an insanity gameplay element, making it an accessible addition to your collection.
Unfathomable

0See it at Amazon!
MSRP: $64.99 USD
Players: 3-6
Playtime: 2-4 hours
Ages: 14+
Unfathomable is a unique game where players must escape a sea of monsters on a boat. It includes a social deduction element, best suited for groups of five or six, where one player is a traitor. It evokes the atmosphere of Battlestar Galactica but within the Lovecraftian mythos. Games can take several hours as players navigate the challenges of identifying the traitor while trying to survive.
Unfathomable offers a different experience from other Arkham games, appealing to fans of social deduction games like Battlestar Galactica.

This expansion adds new prelude cards, three new monstrous horrors (Shoggoth, the Drowned Spirit, and the Grasping Tendril), and new skills, items, and boon cards.
Eldritch Horror

0See it at Amazon!
MSRP: $59.95 USD
Players: 1-4
Playtime: 1-3 hours
Ages: 14+
Eldritch Horror offers a more global experience than the city-focused Arkham Horror. Players travel the world to complete objectives, with a quicker setup and simpler rules that make it more accessible to beginners and intermediate players. It emphasizes strategy and puzzle-solving, with the first game released in 2013.

Other Ways to Play
Beyond the traditional board games, you can explore the Arkham universe through online versions and tabletop roleplaying games (TTRPGs).
The Arkham Horror: The Roleplaying Game
Arkham Horror ventured into TTRPGs with a starter set followed by a core rulebook. I recommend starting with the starter set to get a feel for the rules before moving to the rulebook for further adventures.

MSRP: $34.99 USD
Players: 2-4
Playtime: 1-3 hours
Ages: 14+
The starter set is perfect for beginners, offering a sample campaign and no need for an experienced Game Master.

MSRP: $49.99 USD
Players: 2-6

Ages: 14+
After trying the starter set, you can purchase the Core Rulebook to continue your TTRPG journey in the Arkham Horror universe.
Video Game Versions

A digital version, Arkham Horror: Mother’s Embrace, was released on Steam in 2021. This single-player game, akin to the Mansions of Madness board game, is available on Steam and Switch for an MSRP of $19.99. However, it has received mixed reviews, with IGN giving it a 5/10 due to poor story execution and handling of heavy topics.
Additionally, a digital version of Elder Sign, Elder Sign: Omens, is available on Steam and mobile platforms. Released in 2011, it has received mostly positive reviews and is priced at $5.99.
The Bottom Line
If you're a fan of Lovecraftian mythos-themed games, the Arkham Horror series is well worth exploring. The games offer diverse experiences, suitable for both solo and group play. However, be prepared for challenging gameplay with significant luck elements, which can enhance replayability but also lead to frustration. Setup and learning can take time, though the card games are generally quicker to set up than the board games, even without expansions.
