South Korea's Game Rating and Administration Committee (GRAC) has a long history of spoiling surprises before developers are ready, and it's at it again. As first spotted by Gematsu, the GRAC has rated an unannounced game titled LEGO Skylines, listed under Paradox Interactive, a title that nobody outside of the studio knew existed until now.

What the GRAC listing actually tells us
Based on the rating, LEGO Skylines appears to be a LEGO-themed spin-off of Cities: Skylines, Paradox's city-building series. The connection is right there in the name, and it lines up with how LEGO has been licensing its brand to game developers for years, producing brick-built takes on existing franchises.
Here's the thing: this would also be the first game developed by Iceflake Studios following the split between Paradox and Colossal Order, the original developer behind Cities: Skylines. Colossal Order and Paradox parted ways, leaving Iceflake as the studio now handling the Skylines franchise going forward. A LEGO spin-off would be a relatively low-stakes way to reintroduce the brand under new development leadership.
South Korea's GRAC rating typically surfaces between four and five months before a game's actual release, which suggests LEGO Skylines could be closer to launch than you'd expect from an unannounced project.
Summer Game Fest looks like the likely reveal window
With the GRAC rating now public, the clock is ticking on an official announcement. Summer Game Fest is the obvious candidate. The timing fits, and Paradox would want to get ahead of the leak rather than let a Korean regulatory filing do all the marketing work.
The simulation games genre has seen a real resurgence lately, and a LEGO-branded city builder aimed at a broader, potentially younger audience makes a lot of sense commercially. Cities: Skylines built its reputation on deep, systems-heavy urban planning, but a LEGO version would likely trade some of that complexity for accessibility and visual charm.
Iceflake takes over Skylines dev
Whether LEGO Cities: Skylines keeps the franchise name or sticks with the shorter LEGO Skylines branding remains to be seen. The GRAC listing used the latter, but that could change before launch.
Other games caught in the same rating sweep
The LEGO Skylines entry wasn't the only notable listing. The GRAC also rated Persona 4 Revival, the full remake of Persona 4 developed by P-Studio and published by Atlus. A recent rumor points to a February 2027 launch window for that one, which would make the current rating slightly early by GRAC's usual four-to-five-month pattern.
Also appearing in the same batch: Gears of War: E-Day from The Coalition, Ace Combat 8: Wings of Theve from Bandai Namco Aces, and what appears to be a new version of Eidos Montreal's Marvel's Guardians of the Galaxy, potentially targeting Nintendo Switch 2.
Paradox has not commented on the LEGO Skylines listing. If Summer Game Fest is the plan, an official reveal should follow within weeks. In the meantime, the Cities: Skylines guides collection is worth revisiting if you want to brush up on the franchise before whatever Iceflake has been building finally gets its moment in the spotlight.
