Si Meier's Pirates! is a 2004 strategy/action/adventure computer game developed by Firaxis Games and published by Atari. The game is based on Sid Meier's earlier 1987 game, also named Sid Meier's Pirates!. Overall, the gameplay remains similar to the original game, though it features a 3D game engine (NDL's Gamebryo). Some elements such as sun sighting have been removed, but other features have been added, such as a ballroom dancing mini-game and an improved turn-based land combat system.
