Stronghold [PC Best Buy]

Stronghold is a historical real-time strategy video game developed by Firefly Studios and published in 2001 by Gathering of Developers for Microsoft Windows and Mac OS X. The game focuses primarily on conquest and expansion through military pursuits but also has prominent economic and infrastructure development elements. There is both an economic and a military campaign to be played and both are discussed in the game manual. In the English version, the game takes place in Medieval Britain around the year 1066; however, since there is not always a time limit, scenarios can continue hundreds of years beyond that date.
