Games like 7 days a skeptic

The Chzo Mythos is the collective title given to a series of four amateur, indie adventure games created by Ben "Yahtzee" Croshaw using the Adventure Game Studio development tool. The games are, in order of release and intended play-order, 5 Days a Stranger, 7 Days a Skeptic, Trilby's Notes and 6 Days a Sacrifice. Chronologically, the games do not follow the same pattern.

The series is also sometimes called the DeFoe series, after one of the main characters; the Trilby series, after another main character; or the "X Days a Sauerkraut," based on Croshaw's own references. The author commentary for 6 Days a Sacrifice confirms Chzo Mythos as Yahtzee's intended title, despite referring to it several times on the official sites as the "John Defoe Quadrilogy".
