About

Imagine Earth is a real-time planet simulation and a build up strategy game. Your job as a space colony manager is to explore and populate distant planets. Build up thriving and profitable colonies on a global scale and trade resources and goods into space.
You will experience a massive conflict between the profit goals of the interstellar corporations and the need to preserve living conditions for your people. Exhaust emissions and ground pollution impact the global climate as your colony is growing. Increasing temperatures melt down polar caps and your colonies are destroyed by rising sea levels.
Raise great cities and satisfy their appetite for resources by building power plants, farms and factories. Dig for ideon crystals, pacify riots, research technologies and constructs and maximize your growth while maintaining a healthy ecosystem.
Get ready to deal with threats like asteroid strikes, twisters, wild fires, volcanoes and rising sea levels. Fend off space raiders and alien investors. Coexist and trade with natives, merchants and hostile colonies.
In 2048 huge corporations have divided Earth among themselves and exploited its natural resources to a large extent. Now the discovery of ideon crystals allows journeys into space, while technologically and ideologically almost everything remains the same. The laws of the market are being spread into the universe.
On each discovered planet a competition for economic dominance breaks out. To expand your colony as fast as possible and overcome your opponents you exploit the freely available fossil resources and minerals. Additional money is provided by selling shares of your colony. Take over opposing companies by buying up their shares.
Merchants and technology traders organize the interplanetary trade and will happily buy all minerals and resources you extract from your territory while selling expensive technologies. The same goes for cooperating colonies and alien tribes that live on some of the planets.

so far feels like work in progress. But its really laid back game if you want to chill.
Imagine Earth is a planetary city-building and economic simulation developed and published by Serious Bros. that blends classic management mechanics with a thoughtful focus on environmental sustainability and corporate expansion across the galaxy. Instead of building a city on a flat map like many traditional strategy games, the game presents fully simulated spherical planets that players can rotate, zoom into, and colonize from multiple angles. In this futuristic setting, humanity has begun colonizing distant worlds through corporate initiatives, and players take on the role of a colony manager responsible for developing profitable settlements on newly discovered planets. The central challenge lies not just in expanding infrastructure and population, but in doing so responsibly, since aggressive industrialization can destabilize the planetary ecosystem. This underlying theme gives the game a distinctive identity, transforming it from a standard city builder into a broader simulation about the consequences of unchecked growth. The core gameplay revolves around constructing and managing a thriving colony on alien planets. Players begin with a small landing zone that acts as the foundation of their settlement, gradually expanding outward by building residential districts, agricultural facilities, energy plants, mining operations, and manufacturing industries. Each structure contributes to the colony’s economic and logistical network, requiring players to carefully balance resources such as food, energy, minerals, and consumer goods. Citizens must be kept satisfied with adequate housing and services, while industries need access to raw materials and infrastructure to maintain efficiency. The placement of buildings plays a major role in the overall success of the colony, as certain structures perform better when located near resource deposits or in proximity to complementary facilities. Strategic planning becomes essential when deciding how to distribute industries, residential zones, and ecological protection measures across the planet’s surface. One of the most distinctive aspects of the game is its environmental simulation system. Industrial growth comes with consequences, and excessive pollution gradually alters the climate of the planet. If players rely too heavily on fossil fuels or large-scale manufacturing, carbon emissions increase and begin to trigger environmental disasters such as rising sea levels, extreme weather, and ecosystem collapse. These effects can flood coastal settlements or disrupt food production, creating serious challenges for long-term survival. To counter this, players must invest in sustainable technologies like solar arrays, wind farms, geothermal power plants, and ecological restoration projects. The environmental mechanics encourage players to consider long-term planetary health rather than pursuing short-term economic gains, adding a layer of strategy that is rarely emphasized so strongly in the genre. Beyond basic colony management, the game also incorporates economic competition between corporate factions. Rival companies may establish their own colonies on the same planet, creating a competitive environment where financial strategy becomes just as important as infrastructure planning. Players can manipulate markets, buy shares in competing corporations, or acquire control of rival settlements through economic dominance. This financial system introduces a layer of corporate strategy reminiscent of economic simulations and light 4X games, where influence and capital can be used to shape the development of entire planets. As the campaign progresses, players encounter increasingly complex scenarios involving multiple corporations, limited resources, and escalating environmental risks. The campaign mode provides a structured narrative that follows humanity’s attempt to rebuild civilization after environmental decline on Earth. Each mission takes place on a different planet with its own environmental conditions, terrain features, and resource distributions. Some worlds may contain vast oceans that limit available land, while others feature harsh deserts or frozen environments that complicate agricultural development. These planetary variations keep the gameplay fresh by forcing players to adapt their strategies to different ecological conditions. Alongside the campaign, the game includes sandbox and endless modes that allow players to freely experiment with planetary colonization without strict objectives. Custom planet generation tools also provide additional replayability by letting players design unique worlds with different climates and resource layouts. Visually, the game adopts a colorful and stylized aesthetic that emphasizes clarity and accessibility. Entire planets appear as detailed rotating globes populated by forests, oceans, deserts, and sprawling urban districts. When zoomed out, players can observe the global distribution of their colonies and industries, while zooming in reveals animated structures and bustling settlements. The visual design prioritizes readability and charm rather than hyper-realistic graphics, making it easier to track infrastructure networks and environmental changes across the planetary surface. The interface is designed to support large-scale management, providing clear indicators for resource production, pollution levels, and citizen happiness. The audio design complements the relaxed yet strategic tone of the game. Ambient music tracks create a calm atmosphere while players plan their next development steps, and subtle sound effects highlight the construction of buildings and industrial activity across the planet. While the sound design is not particularly elaborate, it effectively reinforces the sense of overseeing a living planetary colony. Combined with the smooth planetary camera system, the audiovisual presentation contributes to the game’s immersive feeling of managing an entire world. Despite its originality and strong thematic focus, the game does have a few limitations. Some missions may feel somewhat self-contained, as progress from one planet does not always carry over significantly to the next. Additionally, while the environmental systems add meaningful depth, they can sometimes feel unforgiving if pollution spirals out of control before players have access to advanced green technologies. Nevertheless, these challenges also contribute to the game’s strategic complexity, forcing players to carefully plan their development rather than relying on rapid industrial expansion. Overall, Imagine Earth stands out as a unique entry in the city-building and simulation genre by merging planetary colonization with environmental responsibility. Its combination of globe-based construction mechanics, corporate economic competition, and dynamic ecological systems creates a layered strategy experience that encourages thoughtful planning and long-term sustainability. The game successfully delivers both engaging management gameplay and a meaningful message about the balance between technological progress and environmental stewardship. For players who enjoy complex simulation titles and creative city builders, it offers a refreshing perspective on what it means to build a civilization not just on a map, but across an entire planet. Rating: 8/10
I tried to like this but it's carbon tax this, nuclear tax that and on and on on and on. This is just a left wing green new deal made to guilt you into taxing yourself into oblivion and look how well that worked out for aoc, biden and the other eco terrorists! It died cause no one can afford to leave cause of all the taxes put on energy companies! Oh and then corperations used that money to buy up coal plants and then shut them down forcing YOUR energy bills to go up! Screw this game.
good
캠페인 4번째 행성까지 진행했다. 에피소드로 치면 4번째 인지 에피소드1의 4번째인지 구분이 안 가는건 특정 은하계 내에서의 4번째 행성이라고 게임 내 나레이션이 설명했기 때문이다. 게임 진행중 내가 신경써서 진행해야하는 점이 여러곳에 산재해 있어 이곳저곳 계속 화면을 이동해가며 관리해주어야 하지만 문명시리즈에 비하면 매우 덜 움직이는 편이다. 특정 이벤트로 내 건물을 보호해야하는 상황이 생기지만 이 또한 미리 시간을 두고 경고해주기 때문에 빠듯하게 개척지를 운영하는게 아닌 이상 여유자금으로 대처가 가능하다. 건물의 이동또한 내가 선택한 난이도에 따라 무료, 일정부분의 손해로 선택 가능하다. 답답한 점이라면 여러가지로 존재하지만 캠페인 진행으로 이 시스템이 익숙해지게 하기 위해 일부러 천천히 진행되게 해놓은 것 같다. 리뷰 중 배속기능이 없다고 되어있길래 옵션에 살펴보니 b와 v 키로 시간배속을 4배까지 사용가능한 점이 확인 된다. 아마 업데이트가 이루어졌거나. 리뷰어가 잘 살펴보지 않았거나 둘 중 하나인 듯 하다. 문명을 재미있게 했거나 흥미가 있었다면 마침 세일기간이니 이 게임을 시도해보는것도 좋은 선택이다. 2시간 내에 자신의 취향과 맞는지 맞지 않는지 판단하게끔 되어있다. 요즘 스팀에 나오는 게임들처럼 2시간~3시간내에 모든재미를 몰빵해놓고 그 시간 이후 게임이 핵노잼혼파망으로 가는 식으로 설계되어 있지 않다는 것이다. 조금 헤메더라도 캠페인진행에 맞춰 과제(퀘스트)를 진행하다보면(퀘스트 무시하고 하고싶은것 해보는 상황 제외) 충분히 2시간 내에 게임을 계속 즐길지 환불할 지 판단이 가능하다.
very good solid any issues they fix them pretty quick
I liked the theme of the campaign; nice characters and story. It is ironic that the message of this game is sustainability, but I really never looked at the CO2/water levels once after first mission. Only when visiting the Challenge Map - to compare your score vs other players - a green transition was needed, to make the game last long enough so I could increase the company's value / points.
I really tried to like and play this game, but after 17h I just had to surrender. And the thing which broke me were not the game mechanics. These are ok. It was not the horrible, usability, where it feels like no click does what I intuitively expect. I learned to use the game as it is. But what became unbearable was the sermon. The game has NO story. It is one long sermon about climate change, exploitation, evil capitalism, etc, etc. Don’t get me wrong, these are all serious problems, which need to be solved. But there are ways to solve them and there are ways not to. And this game with its bland condescending, kindergarten style of lecturing is a definite how not to.
水多了加面,面多了加水
Just great fun.
