Dune II: The Building of a Dynasty is a real-time strategy game. It serves as the sequel to Dune. 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, Command & Conquer, Warcraft, and many other RTS games that followed.
