City Masterplan is a new city-building game announced by 1:1 Studio, presented as a debut title built in Unreal Engine 5 and featuring true 1:1 scale construction across 24x24 km maps. The studio said players will be able to place roads and buildings without a strict grid, with iconic structures modelled to real-world dimensions.
The developer highlighted a realistic traffic simulation and supply-chain systems, plus a dynamic environment and multiple architectural styles generated with advanced procedural content generation. System requirements on Steam are high, requiring at least 16 GB of RAM and 60 GB of storage, with recommended specs listing 32 GB RAM and modern high-end GPUs.
The title was listed on Steam without a release date but is available to wishlist, signaling a potential new rival to established city-builders.

Trend Themes
-
True 1:1 Scale Simulation — A one-to-one spatial fidelity across expansive maps enables realistic modeling of urban dynamics and infrastructure at real-world proportions.
-
Procedural Architectural Diversity — Advanced procedural generation that yields multiple authentic architectural styles supports vast, varied cityscapes without manually crafted assets.
-
High-fidelity Systems Simulation — Complex traffic, supply-chain and environmental systems simulated at high detail recreate emergent behaviors and operational bottlenecks.
Industry Implications
-
Game Development Platforms — Demand for engines and toolchains that handle massive, high-detail worlds is driving investments in scalable asset streaming and performance optimization.
-
Urban Planning and Smart Cities — City-scale, realistic simulations provide new digital twins for testing infrastructure designs, traffic flows and logistics under varied scenarios.
-
Hardware and Cloud Gaming — Rising system requirements for immersive city simulators are shifting interest toward high-end GPUs, edge compute and cloud streaming solutions.
