Real-Time Base and Unit Production

One loop drives everything: gather a resource, spend it on buildings, buildings produce units, units take ground and protect the harvesters. Time never stops, so construction and combat compete for attention and for the same income. Units are selected with a mouse and ordered directly, production queues run in the background, and a technology tree gates stronger options behind earlier buildings.

Westwood Studios assembled the template in Dune II in 1992, drawing on earlier real-time experiments and on the mouse-driven interface home computers had recently standardised. Its licence supplied a setting where resource harvesting was already the fiction. Consolidation rather than invention was the achievement: sidebar production, direct unit selection, a harvest economy and a technology tree arranged into a shape that finally worked.

Nearly every strategy game since has argued with that arrangement, by extending it, stripping the base out, or collapsing the whole thing onto a single unit. Costs are baked into the format. Real-time play rewards mechanical speed as much as judgement, the opening minutes are usually a memorised routine, and a match can be decided by an economic lead long before anything visible happens.
