No single game in Westwood's catalogue is more consequential than Dune II. Released in December 1992, it did not refine or improve an existing genre — it constructed one from first principles. The mechanics Westwood invented for Dune II became so fundamental to strategy gaming that they became invisible; like the QWERTY keyboard, their ubiquity made their authorship easy to forget.
Design Origins
Brett Sperry had the creative vision; Joseph Bostic built the engine. Sperry wanted to capture the feeling of commanding an army in real time — the stress of simultaneous decision-making, the pleasure of watching a strategy unfold. Board war games had the strategy; they lacked the kinesis. Sperry's insight was that the two could coexist.
Bostic's technical solution was to limit the game's map to what could be processed in real time on the 286 and 386 processors of the era. The fog of war — which concealed unexplored terrain — was as much a performance optimisation as a design choice. Units outside the visible area simply did not need to be computed. The constraint produced gameplay.
The Grammar of RTS
Dune II established conventions that remain standard: right-click to move units, drag-select to group them, sidebar UI for building construction, resource bars, tech trees that unlocked over time. These were not inevitable. They were specific design choices that proved so well-suited to their purpose that no serious competitor ever fully abandoned them.
"We didn't sit down and say, 'Let's design a genre.' We sat down and said, 'How do we make ordering soldiers around feel exciting?' The genre thing only became obvious later, when we saw what Blizzard did with Warcraft."

The three playable factions — House Atreides (human), House Ordos (treacherous), House Harkonnen (brutal) — were differentiated by unit types and special abilities, establishing the asymmetric faction design that C&C, StarCraft, and every subsequent RTS refined.
