Master of Orion III is a turn-based strategy game with the goal of defeating the AI, or other players, in one of three ways. During each turn, the player makes all the decisions that will be performed during that turn, including exploration, colonization, diplomacy, trade, voting in the Senate, technological research, espionage, and the design, construction, and combat deployment of their space fleet. The player can leave most of those decisions to their planetary governors to handle, or they can make changes as they desire."
