Evaluation
Cthulhu Realms launched on July 1, 2016 as a complete digital adaptation of the physical card game. The only DLC — the Full Version unlock — shipped on launch day, giving players access to additional AI difficulty settings, campaign missions, and multiplayer modes. The store description makes no mention of planned expansions or future content, and the game's single news post (from September 25, 2023) was a maintenance update migrating the game to a new server and removing the online play paywall — a technical improvement, not new content. No roadmaps, announcements, or unreleased DLC have been communicated by the developer. The game launched as a finished product and has received no content additions beyond that original release.

How to Play the Game:
In Cthulhu Realms, each player tries to drive their opponent insane or have more sanity than their opponents when the deck runs out.
Each player starts the game with a small deck comprised of initiates, goons and followers. Five cards from the deck form a row of available cards on the table; with more than two players, place three available cards between each pair of players.
Each turn, you start with five cards in hand, playing those cards in order to put locations into play, boost your own sanity or reduce that of others, collect conjuring power to acquire new cards, and remove cards from the game. You can use the power of your locations once each turn. At the end of your turn, discard any cards still in hand and all entities and artifacts that you played.
If you lose all of your sanity, you're out of the game. If you're the only one at the table who's still sane, you win. Otherwise, the game ends when the deck runs out and whoever has the most sanity wins.
