Cities: Skylines has sold 250,000 copies in its first 24 hours on sale.
The figure includes pre-orders, and is a new record for the game’s publisher, Paradox Interactive.
“We would like to offer our deepest and heartfelt thanks to the community for their passionate support and to let them know that we are committed to supporting this wonderful game for years to come, in the same way that we have for our Crusader Kings and Europa Universalis communities,” said Paradox Interactive CEO Fredrik Wester.
“We knew that we had a great game on our hands and so to be able to continue to provide fans of the game with a multitude of new content for it going forward is fantastic.”
Colossal Order’s city sim was being widely described as the new benchmark of the city building genre, Wester added.
“We have forged a strong partnership with them over a number of years through the release of Cities in Motion and Cities in Motion 2, and I am happy to see such a talented team now being widely applauded for their unmatched passion and skill.”
Colossal Order CEO Mariina Hallikainen said the studio was ecstatic to see so many players enjoying the game.
"We at Colossal Order are absolutely thrilled to see so many players enjoying Cities: Skylines and that the Steam Workshop is filling up with amazing content from the modders.
“We are feeling very happy and proud and can't wait to continue working on Cities: Skylines together with the community!"
