Galactic Civilizations IV: Supernova Review – A Stellar Strategy Experience

Galactic Civilizations IV: Supernova, developed and published by Stardock Entertainment, is a turn-based strategy game set in a captivating science-fiction universe. With its classic 4X gameplay mechanics and a host of unique civilizations, this game offers an immersive experience for strategy enthusiasts. In this review, we will delve into the gameplay, mechanics, visuals, and overall experience of Galactic Civilizations IV: Supernova.

A Vast Universe Awaits

At the start of the game, players find themselves in a galaxy where all the prime planets have been claimed. The mid-game is over, and it’s time to make strategic decisions on expansion. While complex treaties may not be an option, strong fleets can protect against individual enemies. The Arceans, who declared war, have suffered defeat, leaving an opportunity to consider launching an invasion of their worlds.

Starbases play a crucial role in the game, mining resources like durantium and antimatter, expanding influence, and protecting systems. Communication starbases are particularly important, as they can even win worlds over without resorting to warfare. With three construction ships at your disposal, the expansion of starbases becomes a key focus, mining and communicating to bolster your civilization.

Diverse Civilizations and Customizability

Galactic Civilizations IV: Supernova boasts a roster of 24 civilizations, each with its own unique style, events, and mechanics. Whether you choose a series regular or a newcomer, the variety in gameplay is abundant. Furthermore, players can create their own custom civilization, tailoring strengths and weaknesses to suit their playstyle.

Introducing the AlienGPT system, Stardock allows players to input text and generate fully playable custom civilizations. This feature adds a layer of creativity and endless possibilities, with generated civilizations featuring interactions and content based on the input provided. The inclusion of AlienGPT ensures that every playthrough is unique and unpredictable.

Exploration and Expansion

The early stages of Galactic Civilizations IV: Supernova revolve around exploration and careful expansion. Probe ships are essential for uncovering the mysteries of the galaxy, while colony ships and construction ships pave the way for claiming new planets and establishing starbases. The allocation of resources and placement of buildings on the right tiles is crucial for generating production, research, food, culture, credits, and influence.

Governors oversee the development of high-quality planets, while other worlds contribute resources to support them. Special buildings, such as the planetary mainframe, offer significant boosts to various aspects of a civilization. As players progress, the research, trade, and espionage mechanics allow for the development of powerful fleets, alliances, and the acquisition of artifacts that can be turned into valuable resources.

Strategy and Diplomacy

Galactic Civilizations IV: Supernova offers a multitude of strategic choices. Players can choose to play tall, focusing on a smaller number of core worlds while prioritizing technology and influence, or expand aggressively to dominate the galaxy. Forming alliances, conducting diplomacy, and engaging in trade and espionage with other civilizations are crucial aspects of gameplay.

Late-game expansion can be approached diplomatically, flipping worlds to your side without resorting to violence. However, it can also be satisfying to build formidable fleets and defend against enemy invasions. The AI opponents provide decent challenges, although they occasionally spread their forces thin, leaving strategic openings for human players. Going for the destruction of enemy systems through powerful Terror Stars is an option, albeit a controversial one.

Deep Customization and Role-playing Elements

Galactic Civilizations IV: Supernova offers deep customization options through the assignment of leaders to ministerial positions, factions, and flagships. These leaders, combined with event chains and the investigation of anomalies, add a layer of role-playing to the game. Anomalies yield artifacts that can be stored or converted into valuable resources, further enhancing the civilization’s growth.

Policies and cultural traditions shape a civilization’s development and determine the path to victory. While the game could benefit from additional variety in some elements, such as anomalies, the core mechanics are finely polished. Galactic Civilizations IV: Supernova encourages exploration, expansion, and strategic decision-making, providing countless hours of engaging gameplay.

Stunning Visuals and Immersive Sound

The visuals in Galactic Civilizations IV: Supernova are visually impressive, with each race featuring unique designs for spaceships and fully built-up solar systems. The game’s science-fiction theme is well-executed, creating a visually diverse universe for players to explore. Short cinematics add an extra layer of immersion to important moments in the game.

The soundtrack of Galactic Civilizations IV: Supernova is unobtrusive, allowing players to focus on strategic decision-making. The sound design enhances the overall experience, although some effects, like the starbase upgrade sound, can become repetitive. Despite these minor drawbacks, the game is visually appealing and easily readable, even when dealing with complex information.


Galactic Civilizations IV: Supernova is a stellar addition to the turn-based strategy genre, offering a rich and immersive experience for players. With its diverse civilizations, deep customization options, and engaging gameplay mechanics, it is sure to captivate strategy enthusiasts. While newcomers may find the initial complexity daunting, investing time to learn the game’s systems will be rewarding.

The inclusion of the AlienGPT system adds a unique twist, allowing players to generate custom civilizations based on their input. The strategic choices, diplomatic opportunities, and role-playing elements make each playthrough a distinct and enjoyable experience. With its polished mechanics, stunning visuals, and immersive sound design, Galactic Civilizations IV: Supernova is a game that will keep players hooked for countless hours.
