Dune II: The Building of a Dynasty (retitled Dune II: Battle for Arrakis in Europe and Dune: The Battle for Arrakis for the Mega Drive/Genesis port respectively) is a Dune video game developed by Westwood Studios and released by Virgin Interactive on Jan 1, 1992. It is based upon David Lynch's 1984 movie Dune, an adaptation of Frank Herbert's science fiction novel of the same name.

While not necessarily the first real-time strategy (RTS) game (elements of which previously appeared in Stonkers, The Ancient Art of War, Nether Earth, Command HQ, and particularly Herzog Zwei), Dune II established the format that would be followed for years to come.^[1][2] As such, Dune II was the archetypal "real-time strategy" game. Striking a balance between complexity and innovation, it was a huge success and laid the foundation for Command & Conquer, Warcraft, StarCraft, and many other RTS games that followed.
