Whether or not Broderbund "borrowed" Polarware's concept for their blockbuster series, there's no mistaking the game's similarities with Carmen Sandiego. You are cast as a spy who is pursuing the evil Dr. X around the continent. Once arrived in a new country, you can buy or obtain clues to the location of the villain, and browse the dossier about that country. If you pay attention to the dossiers, the clues will direct you to the appropriate destinations and ultimately Dr. X's hideout. Despite inferior graphics, the game has one advantage over Carmen Sandiego: there are two excellent multiplayer modes in which up to six players can co-operate together, or compete against each other in their pursuit of Dr. X. Add to that the well-written dossiers, interesting clues, and some strategic elements (for example, you have limited cash with which to buy clues), and the Spy's Adventure games are excellent edutainment titles that are highly recommendable for kids and adults alike. Thumbs up!
