A site that features game simulations based on events in US history. Here is a description of the first game from the website:
"The first game, Mission 1: "For Crown or Colony?," puts the player in the shoes of Nat Wheeler, a 14-year-old printer's apprentice in 1770 Boston. As Nat navigates the city and completes tasks, he encounters a spectrum of people living and working there when tensions mount before the Boston Massacre. Ultimately, the player determines Nat's fate by deciding where his loyalties lie."
