Depends on your group
- Our take
- Its eight investigators are strong, but several BGG players find its Ancient One mechanics the least interesting of the three side-board boxes; buy for the Antarctica theme.
- What you need first
- Just the base game
Eldritch Horror · Expansion
Mountains of Madness
- What it adds
- An Antarctica side board, eight investigators, two Ancient Ones (Ithaqua and Rise of the Elder Things), 156 encounter cards, and the first Adventures and Preludes.
- What it fixes
- Expands the investigator pool and adds Adventures and Preludes to vary setups.
