[Other games] don't encourage the kind of ethical decision making that will be required of future pioneers. Perhaps ECO can offer a solution.

Jordan Shapiro

Eco will help the next wave of decision-makers understand the impact of their choices on the environment, climate, and biosphere. Eco is beautiful, ambitious and important.

Kenneth Karakotsios

Eco is one of the most ambitious and original concepts I've seen in a while.

Jeffrey Matulef

Looks amazing. I've never seen a game concept so beautifully designed around systems thinking and evidence-backed decision-making.

Build a civilization in a simulated ecosystem

Eco is an online game where players must collaborate to build a civilization in a world where everything they do affects the environment. All resources come from a simulated ecosystem, with thousands of plants and animals simulating 24/7. Work together through the player-run government and economy to build the technology to stop a meteor on a collision course with the planet, without polluting the world and killing it off in the process before that even happens. Current Status: Alpha is released and open for players.

Eco Alpha 5, Ecosystem Update

We’ve been working hard getting the Ecosystem update ready for Eco Alpha 5 and looking forward to getting feedback from our early backers. We’ve decided to give it a few more weeks of polish and bug-fixing before we send it out, so we’re moving the Alpha 5 date to Oct 24th. Alpha 4 is available now at strangeloopgames.com/eco however, and all buyers will get all future versions (including a Steam key).

Eco: A Doubly Doomed World

Each world in Eco is fragile, and can be destroyed either through external factors like a meteor striking the planet, or internal forces like poisoning of the ecosystem. Once a world is destroyed, it’s permanently gone, along with everything discovered, invented, and built (as in, the server is physically wiped). Players will be building some…
