City Masterplan, an upcoming Unreal Engine 5 city-builder from indie developer 1:1 Studio, is positioning itself as a next-gen rival to Cities: Skylines with a massive 24×24 km map, freeform roads, true-to-scale skyscrapers, and advanced procedural growth. While early footage looks impressive and Cities: Skylines II continues to recover from its troubled launch, City Masterplan's sweeping realism claims remain unproven in gameplay and the project is still targeting an estimated 2027 release.
