The Last Express

The Last Express is an adventure video game. Players take on the role of an American who accepts an invite by a friend to join them on the Orient Express, days before the start of World War I, only to become involved in a maelstrom of treachery, lies, political conspiracies, personal interests, romance and murder, upon boarding the train. The game is unique in how it was created, its non-linear story, and in how events in the game are conducted within real-time. (wikipedia.org)
