Supreme Ruler 2020 is a grand strategy wargame developed by BattleGoat Studios and published by Paradox Interactive.

The game allows players to choose either Scenarios with a defined scope and objective, or a Campaign "Sandbox" mode where there are no pre-determined victory conditions.

The player controls the economies, the militaries, research, government spending, spy operations (including the launching of satellites), and diplomacy.

The player can lead their people in technological advances and social reforms including globalization, free trade, renewable resources, biotechnology, nanotechnology, robotics, cyborg engineering and neural interface.
