"Making History" Computer simulation

This article I read was about a company that has software called making history. The software is a simulation type program in which students play a game that uses actual events in history. In this case it is World War II. As a single player or multi player game the students take control of one of ten nations and have to compete against other nations and leaders while making economic, military, and policy issues. Like any other simulation game there is always an reaction for any action made. The company claims that this is a constructivist learning environment, which student use a higher-order cognitive skills to show leadership and critical thinking.
Some of the positive things about the game that educators can and materials to the database that they believe was left out and the program can be used to generate reports and track student progress. You can easily see this, because it encourages students to work out a nations problem on their own and have conflict resolutions that would differ from and even would have had better outcomes if history would have played out their way. My concern is that I worry about how much education knowledge is being learned. Yes it is an actual event with real countries, but once started the player will change the outcome and after a half hour it seems to me that the educational factor would be gone and it would just be a game. I feel that, without out actually testing it, that it would make a great fun game to use if students have time to spare but it should not be considered as a teaching tool for social studies. Maybe I'm too sceptical and my thoughts are wrong though.
