Metro Rules of Conduct is a short, simple, and thoughtful game that explores the odd social interactions between public transit riders. Its creator, Kian Bashiri (developer of the equally conceptual You Have To Burn The Rope) describes it as an "accurate simulation of the Stockholm Metro where future travelers can safely learn the unwritten rules without risking making fools of themselves."
As any veteran mass-transit traveler knows, the #1 unwritten rule of public transportation is that eye contact between fellow commuters is strictly forbidden. Being caught glancing (or worse, gawking) at your metro-mates is a major offense. In Metro Rules of Conduct, you get points for sneaking peeks at other commuters' apparel and accessories, but only so long as they don't catch you looking. Press any key to start, then use the arrow keys to direct your gaze.
