A Study in Emerald is a 2‑to‑5 player game that blends the investigative charm of Sherlock Holmes with the cosmic horror of H.P. Lovecraft. Set in 1898, the world is already under the rule of the Old Ones, but a secret anarchist group is fighting to free humanity. Each player takes on a secret identity: a Restorationist battling the ancient beings or a Loyalist defending the status quo. The goal is to accumulate points, but victory hinges on who has the lowest score at the end, with the weaker team losing. The core mechanic is deck building: you use influence cubes to bid on cards that give you control over cities and resources. Meanwhile, open drafting lets you pick from a shared pool, and hand management forces strategic decisions on when to play or hold. The game also mixes hidden roles and area influence, creating tension when teammates can sabotage each other. Point‑to‑point movement keeps the pace dynamic, and team play adds another layer of strategy. With a 90‑minute playtime and a steep learning curve, A Study in Emerald is perfect for fans of mystery, horror, and complex, highly interactive games. If you’re looking for a challenge that blends narrative, deck building, and political intrigue, this title will surprise you—but be ready to dive deep into the rules and intricacies.
