Have You Played? is an endless stream of game recommendations. One a day, every day of the year, perhaps for all time.
Black Closet [official site] is set in an girls boarding school, in which you play as a class president with an unlikely amount of power to interrogate, search and apprehend fellow students who pose a threat to the reputation of your school. But whether that setting appeals or not hardly matters: it is a procedural detective game better than any other.
