Travel in the game costs money, but you can gain more funds by playing the mini-arcade games in each country. These games are very typical (e.g. mazes), and add very little value to the game's promotional goal. They are therefore most likely here only as a fodder-- to make the game last a bit longer. After you win an arcade game, you must answer six trivia questions about the country you are currently in. This is where Off To Europe gets interesting-- the trivia questions are in-depth, and go beyond mere geographical questions to educate gamers about each country's political system, culture, and more. All in all, Off To Europe is one of the better promotional (and free) games for PC, and its design goal (i.e. promoting the (now completed) creation of the ECU) makes it one of the most unique. Worth a try!
