Dune II: The Building of a Dynasty (titled Dune II: Battle for Arrakis in Europe and Dune: The Battle for Arrakis in North America for the Mega Drive/Genesis port, respectively) is a 1992 real-time strategy game developed by Westwood Studios and published by Virgin Games. It serves as the sequel to Dune (a more traditional adventure game), which came out earlier that same year.
While not the first real-time strategy (RTS) video game, Dune II established the format that would be followed for years to come. As such, Dune II is the archetypal real-time strategy game. Striking a balance between complexity and innovation, it was a huge success and laid the foundation for Age of Empires, Warcraft, Westwood Studios' subsequent strategy game Command & Conquer, and many other RTS games that followed.
