LEGO Skylines Leaked by Korean Rating Board — A Cities: Skylines LEGO Game Is Coming

South Korea’s Game Rating and Administration Committee has accidentally revealed games before they were officially announced more times than the gaming industry would like to admit. The latest casualty of this very reliable leak machine is an unannounced game called LEGO Skylines, listed under publisher Paradox Interactive, which received a GRAC rating on April 9, 2026 and was spotted publicly this week by Gematsu. Nobody from Paradox or the LEGO Group has confirmed anything yet — but the name alone tells you almost everything you need to know.

What the Rating Actually Tells Us

Korean ratings board filings are famously sparse. The GRAC entry for LEGO Skylines lists only the game’s title and its publisher — Paradox Interactive. No genre tag, no platform list, no developer credit, no description. Just a name and a company. But those two pieces of information are enough to make the connection obvious.

Paradox Interactive is the publisher behind the entire Cities: Skylines franchise. The original Cities: Skylines launched in 2015 and became one of the definitive city-building games of the modern era. Its sequel, Cities: Skylines 2, launched in late 2023 in a rough state before Paradox shifted development duties away from Colossal Order to Iceflake Studios earlier this year — the same team behind Surviving the Aftermath and Surviving Mars. With the “Skylines” name firmly established as Paradox’s city-building brand, a game called LEGO Skylines with Paradox as publisher is essentially confirmed as a LEGO-themed city builder before a single screenshot has been shown.

According to reporting from Wccftech, LEGO Skylines would likely be the first project developed by Iceflake Studios since taking over the Skylines franchise from Colossal Order — which adds an interesting wrinkle. Whether this is Iceflake’s main focus or a side project running in parallel with Cities: Skylines 2’s continued development isn’t yet clear.

Why a LEGO City Builder Makes Complete Sense

LEGO and city-building games have orbited each other for decades without ever fully colliding in a meaningful way. The original LEGOLAND game from 1999 had players managing a theme park built from bricks, and LEGO’s own website has featured a simplistic City Builder Tool for years. LEGO Fortnite added a survival-crafting dimension to the LEGO gaming space more recently. But a proper, dedicated city-builder built around LEGO bricks and construction — something that marries the accessibility and visual charm of the LEGO brand with the depth and systems of the Skylines franchise — has never been done at this level.

The appeal on paper is obvious. Cities: Skylines’ core loop of zoning, road-laying, utility management, and watching a city grow organically is satisfying on its own terms. Skin that experience with LEGO’s visual language — bright plastic bricks, recognisable minifigure citizens, modular building aesthetics — and you’ve created something that works for kids and adults simultaneously. LEGO gaming has consistently hit that dual demographic better than almost any other gaming brand, and the city-building genre has always had crossover appeal beyond the traditional strategy gaming audience.

Gameranx also noted the interesting possibility that LEGO Skylines could target older hardware as well as current-gen platforms — PS4, Xbox One, and Switch alongside PS5, Xbox Series X/S, and PC — since the graphical demands of a LEGO aesthetic are naturally lower than photorealistic city-building. That would make it significantly more accessible commercially than Cities: Skylines 2, which struggled with performance even on high-end PCs at launch.

The Cities: Skylines 2 Context — Why Paradox Needs This

It’s worth understanding where the Skylines franchise sits right now, because it adds real context to why a LEGO spin-off makes strategic sense for Paradox at this specific moment. Cities: Skylines 2 launched in October 2023 to significant disappointment. The game was technically unpolished, missing key features from the original, and launched without the modding support that had been central to its predecessor’s longevity. The Steam reviews at launch were mixed, and they haven’t dramatically improved.

Paradox’s decision to move development from Colossal Order to Iceflake Studios was a tacit acknowledgment that Cities: Skylines 2 needed a fresh approach. Colossal Order remains involved as a “creative partner” but is no longer leading production. Against that backdrop, a LEGO-branded spin-off that can be developed and shipped more quickly — potentially with simpler technical requirements and broader platform reach — could generate positive commercial momentum for the Skylines brand while Iceflake works on properly stabilising and expanding the core game.

Paradox Interactive has also been navigating a difficult period more broadly. The company went through significant layoffs and cancelled several projects over the past two years. A high-visibility, commercially accessible LEGO collaboration is exactly the kind of announcement that stabilises the narrative around a publisher going through a rough patch.

When Will It Be Officially Revealed?

The timing of the GRAC rating becoming public — with Summer Game Fest on June 5 just days away — is the clearest signal available. Korean ratings filings have repeatedly served as pre-announcement indicators, with games typically being officially revealed within weeks of their rating appearing publicly. LEGO has used Summer Game Fest as a platform before — LEGO Party! and LEGO Voyagers were both shown at last year’s SGF livestream — which makes the June 5 showcase an obvious candidate for a LEGO Skylines debut.

If it doesn’t appear at Summer Game Fest itself, the surrounding showcase season offers plenty of alternatives. The PC Gaming Show on June 7 would be a natural home for a city-builder announcement given the genre’s PC roots. The Future Games Show on June 6 is another option. And if Paradox decides to hold the reveal for a bigger moment, Gamescom at the end of August is where LEGO debuted Batman: Legacy of the Dark Knight last year.

Neither Paradox Interactive nor the LEGO Group have commented publicly on the rating. Based on how these things typically go, that silence probably won’t last much longer.
