Add to campaign dynamic difficulty.

AI players are automatically given a special research topic to make them produce a unit nearly instantly. Now factory throttles represent the true time it takes to manufacture a droid. Difficulty: - Enemy players produce droids using type II, on hard, and type III, on insane, propulsion components. - A new function called camSetPropulsionTypeLimit() can be used to set a specific type level for propulsion to be produced. If nothing is passed to it then this feature is disabled (default).
