    Mansions of Madness: Beyond the Threshold

    Worth it

    Half the price of a big box with two well-liked scenarios (Gates of Silverwood Manor); content stays close to the base game.

    Mansions of Madness: Horrific Journeys

    Worth it

    Divisive but many BGG players call it their favorite; 10:50 to Arkham is highly rated.

    Needs: Just the base game

    Adds: Four investigators, new monsters, train and ship tiles, time-rift and lost-in-time-and-space mechanics, and three app scenarios.

    Fixes: Adds new mechanics and themes beyond haunted houses, including some of the highest-rated scenarios.

    Mansions of Madness: Sanctum of Twilight

    Depends on your group

    Good investigators and the well-liked Twilight Diadem scenario, but its tiles rarely appear elsewhere and Behind Closed Doors is notoriously hard.

    Needs: Just the base game

    Adds: Two investigators (Lily Chen, Charlie Kane), Silver Twilight Lodge tiles, a contention mechanic and two app scenarios.

    Fixes: Breaks away from the base-game theme with a cult-lodge setting at small-box price.

    Strong investigators, but its mechanics and tiles stay within its own scenarios; BGG players suggest buying it last.

    Needs: Just the base game

    Adds: Four investigators, new monsters, jungle and ruin tiles, exploration mechanics and three app scenarios.

    Fixes: Gives veteran groups a distinct jungle-expedition setting with strong new investigators.
