What the developers have to say:

Why Early Access?

“As a small indie studio we need all the feedback we can get. Adding new features and balancing the game dynamics is a quite complex task within the global simulation of each planet. Additionally the income of early access helps us to stay independent. We want to take the time to evolve this game into a little sensation. Something that has never been played this way before. The first planet colonization and climate survival thriller game.”

Approximately how long will this game be in Early Access?

“We plan to release Imagine Earth in late 2016.

There is a new alpha release every 3 to 4 weeks.”

How is the full version planned to differ from the Early Access version?

“Currently there are three big things left to do:
1. Add more interaction with other (AI) companies and their cities: Trading, taking over, sabotage, ...
2. Make the general gameplay more diverse.
3. Iterate until the whole thing is perfect ;-)”

What is the current state of the Early Access version?

“Please read the feature list in the game's about section.”

Will the game be priced differently during and after Early Access?

“No, the release price will be the same.”

How are you planning on involving the Community in your development process?

“We need your thoughts, ideas and direct feedback on what you experience during gameplay. To keep you updated about the actual development process we are writing a friday report every week and there's a major update release once a month. The complex interconnections between the buildings are a hell of a balancing job on which your opinion is highly appreciated. Name the features you would be most excited about and let's make this thing a unique experience together.”

Take Part in MonoGame Testrun

Hi, as announced with the last alpha release, we are replacing the underlying game framework XNA with MonoGame. This makes it a lot easier for us to find bugs and enhance the performance of Imagine Earth (e.g. by using DirectX 11). In addition it enables us to port Imagine Earth to other platforms, though this is not something we plan to do at the moment.

Since technological changes often come with bugs, we need your help to test the new MonoGame version of Imagine Earth.

We have a beta version available for you to test. This will not affect your savegame or anything and you can switch back anytime if you are experiencing problems.

All you need to do is:

  • open the Imagine Earth properties in Steam, go to the "BETAS" tab
  • enter the access code "monogametest" and press the "check code" button
  • finally select the "monogame" beta and accept. Now Steam will load the changed files
  • Try the game and let us know if it works

Alpha 22 "Emission Levy"

Another month is over and Alpha 22 is ready for you. In short:

  • Emission levy to balance global pollution
  • New take over rules
  • New preview images in tech menu
  • Harvesting forests and mining rocks earns goods
  • Cold temperatures reduce the harvest of your farms
  • Changed savegame directory structure
  • Porting to MonoGame prepared
  • Bugfixes and balancing ...

Emission Levy

The emission levy (as shown in the image above) is a new rule introduced to add some fairness to the aspect of global pollution. Once the climate balance of the planet falls into negative, the companies with high emissions have to pay charges to the companies whose emissions are below the average. A good incentive to reduce emissions.

New Take Over Rules
The last alpha version 21 introduced to possibility to take over opponent cities by buying 50% or more of their taxes. We have collected your feedback and added our own ideas to further refine this.

The value of a colony itself is now much higher to make sure freshly build colonies are worth more than 5-10% shares. Additionally we changed the rules for watchtowers (!):
  • A watchtower that has no connection to a colony center will be lost. This can happen when (A) an opponent takes over a colony or (B) a connecting watchtower is destroyed.
  • Watchtowers that have no owner and are adjacent to your colony can now be taken over by paying some money.
This makes the whole process of taking over opponent colonies a bit more interesting and challenging.

New Preview in Tech Menu
All buildings and their upgrades have received new preview images that are show when hovering them in the tech menu.

Harvesting Forests & Mining Rocks
With the new version you no longer earn money when harvesting forests. Instead you receive goods every tick until you cancel the harvest process or the forest is uprooted.

This is also the case for rocks. Mining them now also gives you goods that can be used by your population.

Important: Harvesting forests with the chainsaw tool and blasting rocks will give you only a part of the goods and you will need a storage to keep them, because everything is earned at once.

Influences of Temperature
The temperature of a planet field is shown at the bottom left of the screen in the field info panel. Farms and some forest types are affected by cold temperatures. The following screenshots shows an industrial farm that was build on a field with a temperature of -8°C. This extremely reduces the amount of food produced, as shown in the message panel.

Changes to Savegame Directory Structure
We have simplified the directory structure of savegames (left old, right new). When you start the new released version of Imagine Earth everything should be changed automatically. However, it's always possible that something goes wrong. If savegames are missing please check the directory structure and write a support request to

MonoGame Portation
Imagine Earth has been developed using Microsoft XNA - an easy game framework that is no longer in active development. Luckily members of the XNA community started to develop MonoGame which now can be used as an open source replacement. This makes it a lot easier for us to find bugs and enhance the performance of Imagine Earth (e.g. by using DirectX 11). In addition it enables us to port Imagine Earth to other platforms, though this is not something we plan to do at the moment.

Long story short: During the last weeks a lot of time went into porting Imagine Earth to MonoGame - especially sounds and music. Since a new technology might also introduce new bugs we will start a public test in the next days. Stay tuned if you are interested in helping us to make sure everything runs smooth.

“The demo is quite charming... There's already evidence of a decent game”
Rock, Paper, Shotgun

“Imagine Earth is a refreshingly streamlined and charming apporach to civilization sims - and one with plenty of room to grow as it wades through Early Access.”

“This environmentally-conscious title may very well prove to generate news in the months to come.”

About This Game

Imagine Earth

Imagine Earth is a real-time world simulation. Your job as a colony manager is to explore and populate distant planets. Build up thriving and profitable colonies on a global scale without destroying your homeworld. Deal with threats like meteorite strikes, twisters and wild fires. Coexist and trade with natives, alien investors and hostile colonies, dig for Ideon crystals, pacify riots and master the perfect balance of production and consumption for many available constructs and technologies.

The Challenge

Raise great cities and satisfy their growing appetite for resources by building power plants, farms and factories. You will soon encounter the conflict between the profit goals of interstellar corporations and the need to preserve the living conditions for your people. As your colony grows it is getting a problematic impact on the planet in terms of exhaust emissions and pollution. The challenge is to deal with whole planetary ecosystems and their natural limitations in fossil resources and environmental resilience. Do research for renewable energy sources and develop sustainable production lines to avoid overgrowth and climate collapse on your new home world. Can you prevent tremendous desolation and lead your colony into wealth and prosperity?


  • Play on a globe instead of a map
  • Campaign with 6 missions and planets introduces into the gameplay
  • Goals guide you through the expansion of your colony
  • Development of over 30 colony buildings with individual upgrades
  • Global simulation of local pollution and worldwide emissions
  • Disasters: Chemical spills, oil slicks, radioactive contamination, wild fires, tornadoes, volcanoes, dying forest and growing deserts
  • Melting polar caps will raise sea levels and flood your coasts in case of global warming
  • Sandbox mode to generate and edit your own planets
  • Competition and Free Play mode let you build your colony in a race against AI players or for yourself.

Climate Change

Climate change is apparently a very underestimated threat in computer games. The idea behind Imagine Earth is to put the most serious background of latest human history into a thrilling and motivating game flow. In that context the game is an experimental world simulation or a climate survival thriller. It directs this quest to the player. What would your civilization end up like and what could you do if you were in charge and no one else around to blame? Imagine Earth offers the biggest possible freedom of choice to the player so he can find his own answers and development strategies.

“Exploring the balance between growth and sustainability is the key to success in this game.” - Martin Wahnschaffe, Design & Code

One of the best planetary colonization games I played. Not only with beautiful graphics, but also smooth gameplay and story line.

Can only wish the strategy aspect became a tad deeper...

Early Access Review
The game combines resource management, technology planning, and careful positioning at a real-time strategy game pace. It is easy to pick up the basics, but definitely takes skill to get good at it.

The gameplay is great, despite the graphics not being the best on the market. Considering this is an indy title, it really needs to get more attention as a great addition to a difficult-to-please genre of players.

Look at the negative comments for the game - none of them complain about gameplay. Its all taste-based comments or something that's not an issue like expecting world-class graphics from an indy team. The negative comments don't complain about the gameplay, because the game is fun and challenging.

Would love to see how this game ends up at release. Fantastic game so far - This could become a benchmarking game for the genre.
