Publisher Paradox Interactive reports that Cities: Skylines has sold 12 million copies across all platforms.

First released in 2015, the game switched to Switch three years later. Despite retaining many of the same features as previous versions, gamers have encountered numerous performance issues in the Switch version.

Mariina Hallikainen, CEO of developer Colossal Order, said about the 12 Million sales:

“We are grateful for how active the Cities: Skylines community has been, and we are delighted to see them share their passion for city-building games with us. It was a dream come true to see the game resonate with so many players over all these years. We continue to listen to the feedback we’ve received and are committed to working hard to bring even more joy to our fans in the future.”

To celebrate this situation, a birthday patch was applied to the game on PlayStation and Xbox. Unfortunately, this patch did not come to the Switch.
