control the spice", so a resource-based strategy video game would be a good idea. It was around this time that employee Graeme Devine (who later founded Trilobyte) introduced to everyone at the Virgin office a real-time strategy game on the Sega Genesis / Mega Drive console called Herzog Zwei (1989). Clarke-Willson described it as a game where the player "kept clicking on stuff and then zooming off to another part of the screen. It was very hard to keep track of what was going on as an observer. Still, everyone liked it, it had fast action, and it was a strategy game". Virgin staff, including Clarke-Willson and Seth Mendelsohn (who later worked on the Ultima series), then went to Westwood Studios to talk about making a Dune game. According to Clarke-Willson, "Westwood agreed to make a resource strategy game based on Dune, and agreed to look at Herzog Zwei for design ideas". It later turned out that Cryo's game of the same name was not cancelled, and Westwood's real-time strategy game was called Dune II as a result. Westwood Studios co-founder and Dune II producer Brett Sperry said in 2008 that conceptualization for the game began when Virgin president Martin Alper approached him with the offer of using their Dune license to produce a game, with the understanding that Cryo's Dune had been cancelled. In terms of video game design, Sperry said: "The inspiration for Dune II was partly from Populous, partly from my work on Eye Of The Beholder and the final and perhaps most crucial part came from an argument I once had with Chuck Kroegel, then vice president of Strategic Simulations Inc ... The crux of my argument with Chuck was that wargames sucked because of a lack of innovation and poor design. Chuck felt the category was in a long, slow decline, because the players were moving to more exciting genres ... I felt that the genre had a lot of potential – the surface was barely scratched as far as I was concerned, especially from a design standpoint. So I took it as a personal challenge and figured how to harness realtime dynamics with great game controls into a fast-paced wargame". He also stated that, while "Herzog Zwei was a lot of fun", the "other inspiration for Dune II was the Mac software interface", referring to the "design/interface dynamics of mouse clicking and selecting desktop
