Leaked Lego Game Reportedly Combines SimCity with Lego Building

A recent classification from The Game Rating and Administration Committee of Korea points toward an intriguing collaboration: Lego and Paradox Interactive appear to be developing a brick-based iteration of the acclaimed Cities: Skylines. The title surfaced in a fresh wave of certifications recently highlighted by Gematsu, appearing alongside Persona 4: Revival and a Nintendo Switch port of Marvel’s Guardians of the Galaxy. While the listing omits the word “Cities” from the title, the involvement of Paradox confirms its identity as a spinoff of their signature city-building franchise.

Although the filing lacks specific gameplay details or a projected launch date, the formal stamp of approval from an international regulatory board confirms the project’s existence. While Paradox is listed as the publisher, the specific development studio tasked with bringing this plastic-brick metropolis to life remains under wraps.

Colossal Order served as the creative force behind Cities: Skylines and its sequel, yet Paradox has remained tight-lipped regarding their current internal workload. Cities: Skylines 2 arrived in 2023 burdened by significant technical hurdles—most infamously, an optimization issue that saw the game rendering individual teeth for every resident, putting a massive, unnecessary strain on hardware. These performance stumbles persisted for years, and the long-anticipated console version continues to linger in development limbo.

By late 2025, Paradox reassigned Colossal Order to an unannounced initiative, tasking Iceflake Studios—veterans of the survival genre with Surviving the Aftermath—with the ongoing support for Skylines 2. While community forums still echo with reports of lingering AI inconsistencies, the general sentiment suggests that Iceflake is steadily steering the ship back toward smoother waters.

Lego, meanwhile, has been aggressively broadening its interactive portfolio. Moving beyond simple adaptations of blockbuster films like Star Wars or Batman, the brand has ventured into survival gaming with Lego Fortnite and reimagined existing IP through brick-based lenses in titles like Lego Horizon Adventure. Furthermore, recent releases such as Lego Batman: Legacy of the Dark Knight have broken the mold, trading traditional linear stages for expansive open-world gameplay centered on gadget-driven exploration and dynamic action.

Given the enduring popularity of the classic Lego City toy line, a sandbox city-builder feels like a natural and highly anticipated evolution for the brand.

While an official reveal remains pending, the approach of the summer event season—including Summer Game Fest 2026—suggests that more information regarding Lego Skylines will likely emerge in the coming weeks.
