Welcome to Arcology One

A door closes somewhere in the Laser District. Beyond it, a machine that has outlived several owners begins another shift. Upstairs, someone is watering a plant. Farther up, a family is debating a view they have argued about for generations. This is the world of Arcology Project.

Concordia is still here

The original arcology opened in 2090. Four hundred years later, its core survives inside a much larger structure, built and rebuilt by people with different resources, different technologies, and different ideas about a good life. Most residents would not trade it for anywhere else. People call the first arcology Concordia.

There is more behind the door

Story preview: the story in development begins with an inheritance, conflicting records, and the hope of a fresh start. Its mysteries grow out of the city’s ordinary business: who owns a room, who has its key, and whose version of the past is written down. The inheritance campaign is not yet a playable quest line.
