About Eco

✦ AI summary

You must save the planet from an imminent meteor strike by building civilization and managing resources, but every action ripples through a living ecosystem where chopping trees destroys habitats and pollution poisons crops. Balance progress with environmental protection by specializing in crafts, trading with other players, passing democratically-voted laws backed by scientific data, and building a player-run economy—all while the clock ticks toward doomsday.

Enter the world of Eco, a fully simulated ecosystem bustling with thousands of growing plants and animals living their lives. Build, harvest, and take resources from an environment where your every action affects the world around you. An imminent meteor strike threatens global destruction. Can you save the world without destroying it in the process?

Construct buildings and towns, tend to your farm, hunt wildlife, build infrastructure and transportation, craft clothing, build power plants, and research new technologies. Specialize in a craft and trade your goods to other players. Develop your civilization and sculpt your planet.

As your civilization grows, you’ll need to analyze data from the simulation; evaluating the impact you have on your world. Use this data as evidence in proposed laws, restricting harmful activities without disrupting the advancement of technology. Balance your individual needs with the needs of community, all while maintaining the state of the ecosystem. The future of your world is in your hands.
Every organism in Eco exists as part of a detailed simulation; a disruption in one species can have cascading effects across the planet. Chop down all the trees, and habitats for creatures will be destroyed. Pollute the rivers with mining waste, and your farms will become poisoned and die. The ecosystem supplies the resources you and your community will need to stop the meteor. Manage your pollution, mining waste, hunting, and resource collection to balance your effect on this system.
Eco is built on a rich ecological simulation. All the data generated from the interaction of plants, animals, climate, and players can be searched and analyzed using in-game graphs and heat-maps. Use the collected information as scientific evidence support to proposed laws. The ability to successfully debate using scientific evidence is your greatest weapon against the destruction of your world.
Establish and maintain your own set of laws and government, which are enforced automatically by the game. Draft a proposal to limit clear-cutting in a protected forest, incentivize green energy solutions over fossil fuels by providing tax subsidies and penalties. Participate in elections for world leadership, allowing you to set tax rates and allocate community money. Use a programmable law system to make dynamic and flexible rules for the community, passing them by vote. Construct a wide variety of governments; from tightly-regulated dictator-states, to tax-and-spend subsidy programs, or even lawless communities relying on trust.
Your skills increase based on your food and shelter. By consuming a highly nutritious variety of food and building an elaborate home you will rapidly increase your skill points. Skill points can be spent on skills like farming, hunting, trade, engineering, research, and more. Contribute to the greater good while increasing your own personal success.
In the player-run economy, you achieve the most when you specialize and trade both goods and services. Create stores to buy and sell goods you need asynchronously with other players. Setup contracts within the game’s quest-like labor market, soliciting other players to perform specialized work for you in exchange for payment. Build complex crafting machines and charge a fee for players to use them. A thriving economy in Eco can be both a powerful tool for progress, or a dangerous threat to the environment.

To grease the wheels of commerce, you can create your own currencies, backed by fiat or by resources. Manage the value of your currency relative to others by setting exchange rates at asynchronous currency exchanges. Sell items at stores and collect credit from other players. Eco is designed for rich asynchronous play, allowing many players of many disciplines to contribute to one another’s goals at separate or simultaneous times.
All of the world’s resources originate from its environment, which is affected by your actions. While a meteor looms over head — set to strike the planet in thirty days — a more subtle threat grows from player-interaction with the environment. Without careful attention, ecological destruction can destroy civilization before the meteor even strikes. To ultimately succeed, you and your community will need to use the tools of government and economy to find a balance between progress and protection.

I woke up in a world! I walked around, talked to a few inhabitants and decided I set up my tent somewhere in the middle of everyone. First thing I wanted to do, is to make a simple house. I cut down some trees and took some dirt to make a nice simple house. Then it was time to decide what I wanted to specialize in! Looking at my neighbours, the thing that was missing was a good cook, so I became one. I made delicious meals and traded that with my neighbours for resources only they could produce. My house became prettier by time and by that time I had a little farm going to supply for my cooking. Some people in the world were good at gathering, so I decided to contract them to harvesy my goods for some good food in return, a benefit for both sides! Then the next step in civilization came, making a town. A bit further away from my own house I made the Town Hall, invited the surrounding people to join the town. Suddenly we had a small community with shared common goals. Making infrastructure, setting up laws and ask around what desires the town folk had, was next on my agenda. We grew big, we benefitted of each others professions and made nice infrastructure to allow f…

Hmmm, I wanted to have the patience to get past the glacially slow and terrible tutorial. I unfortunately did not, I could not get the construction UI to get on my side, and I don't even think this should be a non skippable introduction to the game, whatever that is, I never got to find out. What I did find is that the appalling non intuitive UX throughout would not work for me because good UXD is table stakes for any game, it is as important as the gameplay itself to me. Yes I can find videos and threads to "figure it out" but that is unacceptable to me at this price point. Cannot recommend.

Out of nearly 40 minutes of playtime, about 5 of those minutes were used to create a character, and the rest were used trying to load games. Load times are insane for both single player and multiplayer games.

Great game to play together with friends or make new friends in the community!
