Where in the World is Carmen Sandiego? is directed at children but can easily teach an adult a thing or two. Geography is the primary subject of the game which concentrates on 30 cities from around the world.
A joystick or keyboard can be used as the only controls required are making selections from menus. At each location players can investigate, check their destinations, depart by plane, or access their crime computer.
Investigating is where all the facts are learned. Although you only make menu selections, not in depth investigating, you do have to manage your time and study the clues. About half of the game is spent using the included World Almanac. For example, someone who saw the suspect will say the person had a flag with a blue cross on it. One of the destinations available to the player is Oslo, the capital of Norway, a country with a blue cross on its flag. Checking the destinations before investigating can help point players in the correct direction.
Other clues learned will be physical attributes and hobbies of the suspect. These clues must be entered into a crime computer in order to get a warrant for the appropriate suspect. The instructions include a description of each of the ten possible suspects. Even if a suspect is captured they will continue to appear throughout the game so that you cannot use a process of elimination to determine who the next suspect will be.
