What is Cthulhu Realms?
This deckbuilding card game has solo campaign missions and matches against AI or other players. During each match, you acquire cards, play locations with reusable powers, and use five-card hands to restore your sanity or reduce opponents' sanity. You win by being the last sane player or retaining the most sanity when the deck runs out.
