Quick answer: Eco worlds usually die from one of three things, and none of them is people losing interest in the game. The meteor timer was set too short, so the world ended while the group was still building. The collaboration setting did not match the group, so either nobody needed anybody or four friends got blocked waiting for a specialty nobody took. Or the server was not reliably there, and a game where the world keeps simulating without you punishes that harder than most.
Eco is unusual, and that is why it fails unusually
Most survival games are forgiving about how you run them. Log off, come back, the world waited.
Eco does not wait. Plants grow or fail to. Pollution spreads through soil and water. The economy your players legislated keeps running. The meteor keeps approaching. All of it happens whether or not a single person is connected.
That single design decision is why Eco servers fail in ways other servers do not. A world is not a save file you return to, it is a process that has been running in your absence. Interrupt the process badly enough and the thing people were invested in is gone.
Cause one: the meteor timer
This is the most common, and the most avoidable.
Groups consistently underestimate how long Eco takes. The tech tree is long, the economy takes time to form, and a group of people who have not played before will spend the first week just working out what they are doing. Set a deadline that felt generous when you created the world and there is a real chance it arrives while everyone is still mid project.
The settings live in two places. HasMeteor in Difficulty.eco.template controls whether one spawns at all. CreateMeteor and MeteorImpactDays in Disasters.eco control the rest. You can also reach server configuration in game with /serverui, which is usually faster for something you want to adjust rather than set once.
The practical advice: set it longer than feels right. Extending a deadline mid game is trivial. A world that ended while people were still enjoying it cannot be brought back, and that group will not restart with you.
Cause two: collaboration set wrong for the group
This one is quieter and it kills servers without anyone identifying why.
Eco's collaboration presets change how expensive it is for one player to do everything. The mechanic is CostPerAdditionalSpecialty, which sets how many extra stars each additional specialty costs someone who already has some.
On high collaboration, a player who wants to be a farmer and a smith and a carpenter pays steeply for the third and fourth. So they do not. So they need someone else. That interdependence is what produces the economy and the politics Eco is known for.
On no collaboration, everyone can do everything. What follows is five people quietly building five self sufficient bases and never having a reason to speak. The server does not collapse dramatically, it just gets boring and people stop logging in.
But high collaboration has its own failure mode, and it hits small groups. Four friends on high collaboration can hard block: nobody took the specialty they now need, and getting it costs more than any of them can spend. That is a genuinely stuck world.
Match the setting to the group. Small and private tends toward lower. Larger and public tends toward higher. Getting this backwards is a slow death either way.
Cause three: the server was not reliably there
Because the world keeps running, downtime in Eco costs more than downtime elsewhere.
If someone self hosts on their own PC, the world exists only while that machine is on. For a group that plays at the same times that works. For a group where people log in at scattered hours it becomes a nightly favour asked of one person, and the answer eventually becomes no.
There is also a data retention rule that catches groups who take a break. Inactive free server storage does not last indefinitely on most platforms, and an Eco world represents a lot of collective work to lose to an email nobody read.
The practical version: if your group intends to run a world for months, put it somewhere that does not depend on one person's PC being on, and keep your own backup regardless of what your host does.
What a server that survives looks like
The worlds that make it to the meteor tend to share a few things, and none of them are about hardware.
A deadline the group agreed on, rather than one the admin picked alone on day one.
A collaboration level matched to the size of the group, revisited if the group grows.
Somewhere reliable to run, because the simulation not pausing means availability is a feature and not a luxury.
Room to grow. Eco memory use follows world state, not player count. A fresh world barely uses anything. The same world after months of cleared forest, mines, settlements and legislation is tracking vastly more. A server sized exactly for week one is a server that struggles in month three.
That last point is why our Eco hosting runs 4 to 12GB tiers from EUR 4 a month. Start at 4GB for a fresh world, move up as it accumulates. Buying the largest tier on day one is paying for a world you have not built yet.
FAQ
How long should I set the meteor timer? Longer than feels right, especially for a group new to the game. Extending it mid game is easy, and a world that ends early cannot be recovered.
Where are the meteor settings?
HasMeteor in Difficulty.eco.template, CreateMeteor and MeteorImpactDays in Disasters.eco. The /serverui admin command reaches server configuration in game.
What collaboration level should I use? Lower for small private groups, higher for larger public ones. High collaboration on a group of four can hard block when nobody has taken the specialty they need.
Does the world really keep running when nobody is online? Yes. Plants, pollution, the economy and the meteor timer all continue. That is why hosting reliability matters more in Eco than in most survival games.
Why does my Eco server use more memory than it did at the start? Memory follows world state. Cleared forests, mines, settlements and every altered block are all being tracked. A developed world is far heavier than a fresh one on identical hardware.
How much RAM does an Eco server need? 4GB for a fresh world with a small group. 8GB or more once the world has months of development in it.
