High Quality Content by WIKIPEDIA articles! Stronghold is a historic real-time strategy (RTS) game developed by Firefly Studios in 2001. The game focuses primarily on conquest and expansion through military pursuits, but also provides space for economic strategy and development. There is both an economic and a military campaign to be played and both are discussed in the game manual. The game takes place in Medieval England and Wales around the time of AD 1066; however, since there is not always a time limit, scenarios can continue hundreds of years beyond that date.
