Astrologaster is a humorous "biographical" adventure game based on real-world historical figure Simon Forman, Elizabethan doctor, astrologer and alchemist. Players take the role of Forman, casting astrological charts (using intuitive touch actions to manipulate beautiful papercut charts inspired by actual astronomical instruments of the day) to answer questions about the future, the past, and sickness. If patients are happy with the predictions and treatment received, the player gains status, wealth and influence over London society. If patients are dissatisfied, the player runs an ever greater risk of, being revealed as a charlatan, thrown into prison or sued for malpractice by the royal college of physicians. As the player navigates the spider's web of patients, emergent narratives reveals deeper intrigues and makes us wonder whether it was really all 'written in the stars'.Simon Forman is a well-known historic figure of the age, he was considered a sage by some and a charlatan by others. His dealings were occasionally considered notorious, but the casebooks he left behind offer a unique documentary insight into medical practice at the time and the society in which he lived. Funding from the Wellcome Trust has allowed a team of academics at Cambridge University, led by Lauren Kassell, to digitise the records of 80,000 consultations by Forman and his associate Richard Napier, which form Astrologaster is based on.
