Cities: Skylines upheaval: Developer and publisher announce “mutual” breakup

Paradox Interactive announced that long-time Cities franchise developer Colossal Order and the publisher have “mutually decided to pursue independent paths,” with Colossal Order moving on to new projects and Paradox handing the Cities: Skylines franchise to its Finnish studio Iceflake. Acquired by Paradox in 2020 and known for Surviving the Aftermath, Iceflake will take over work on Cities: Skylines II—including free updates, expansions and content packs from the start of 2026—and will also handle the long-awaited console ports originally planned for 2023. The company provided few details on the split, leaving the rationale and near-term implications for continuity and development direction unclear.

Analysis

Paradox Interactive announced a mutual split with Colossal Order, ending a relationship that spanned "well over a decade," and transferring stewardship of the Cities: Skylines franchise to its in-house Finnish studio Iceflake, with the public forum post made Monday morning. Colossal Order will pursue new projects while Iceflake—acquired by Paradox in 2020 after releasing Surviving the Aftermath—will assume responsibility for Cities: Skylines II free updates, expansions and content packs beginning in 2026 and will handle the long-awaited console ports that were originally planned to ship alongside the PC version in 2023. The company provided few details on timing or the rationale for the split, leaving near-term execution risk and community reaction as the principal unknowns. Market signals included a mildly positive overall sentiment score of 0.25 and a low market impact score, reflecting limited immediate financial disruption but highlighting the importance of execution, community trust and the delivery timetable for updates and console releases under Iceflake's stewardship.

Key Decisions for Investors

• Monitor Paradox's detailed 2026 roadmap and early execution milestones for Cities: Skylines II updates and the console port schedule before increasing exposure, because responsibility shifts to Iceflake only from 2026 onward
• Maintain a neutral-to-cautious stance on Paradox positions until Iceflake demonstrates timely content delivery and positive community reception, as the announcement is sparse on specifics and continuity risk is material
• Consider hedging or limiting new purchases given the execution and timing uncertainty around delayed console ports that were planned for 2023, and track Colossal Order's new-project announcements as a potential competitive or partnership risk
