City planners in Stockholm, Sweden are using city-building game Cities: Skylines to design a new city district, with the assistance of publisher Paradox Interactive.

The development project, Norra Djurgårdstaden, will include 12,000 residences and 35,000 workspaces, focusing on sustainability and supporting an expanding population.

Planners and officials will engage in a workshop over the first weekend of September, experimenting with the district plans in Cities: Skylines to investigate the project's viability and explore options for its design.

The game's community has already contributed ideas, and modder Alexander Oberroither will fly to Stockholm to take part.

Paradox COO Susana Meza Graham praised the city and the Swedish Building Services for "their ambition to find new and forward-thinking ways of solving real societal challenges," in a press statement released yesterday.

"We undertook a previous project with Minecraft and Mojang which developed into a project spanning the world, and we look forward to seeing what using Cities: Skylines as a tool will generate," said Swedish Building Services' Erik Kalmaru, citing games' strengths as citizen outreach tools.

"Computer games have shown to be a very effective tool to build engagement and generate ideas, but also to visualise the process."

Cities: Skylines is now available for Mac and PC; a Natural Disasters expansion is due this season.
