What is stronghold?

Stronghold is a medieval strategy game series developed by Firefly Studios. The game allows players to build and manage their own castles, recruit armies, and engage in battles against other players or AI opponents. Stronghold includes various game modes, including a single-player campaign, multiplayer modes, and a free build mode where players can freely design and build their own castles without any restrictions. The game also features a detailed economy system that requires players to manage their resources carefully to ensure success in battles and in the overall running of their fiefdoms. Stronghold has earned critical acclaim for its attention to historical detail and immersive gameplay, and has spawned several sequels and spin-offs that continue to refine and expand upon the original game's core mechanics.
