Giantess Playground is in a legal dispute between its developer GiantessGameUE5 and co-developer AGGRESSIVE MASTERY, who released the game on Steam Early Access on August 14 without the developer's permission. The developer is pursuing legal action and has not received owed revenue.
Giantess Playground, a giantess city-destruction sandbox game, launched on Steam as Early Access on August 14, 2026, published by AGGRESSIVE MASTERY. The game lets players control a giant woman destroying a city or play as fleeing citizens. It was originally distributed to Patreon supporters starting in 2022, and a co-development arrangement with AGGRESSIVE MASTERY began around January 2025. The Epic Games Store version entered Early Access on July 23, 2025.
Developer GiantessGameUE5 immediately disputed the Steam release, claiming it happened without permission and that they are pursuing legal action. According to GiantessGameUE5, a conflict over release policy and revenue emerged in June 2026. They say AGGRESSIVE MASTERY demanded higher plugin fees and 50% of sales, while most development work remained with GiantessGameUE5. After proposing to end the co-development and forfeit Epic Games Store revenue, GiantessGameUE5 claims AGGRESSIVE MASTERY removed them from the development accounts and released the Steam version unilaterally.
GiantessGameUE5 says they have not received owed revenue and are collecting evidence for legal action. As of the most recent story, AGGRESSIVE MASTERY has not issued a public rebuttal, and the Steam store page remains active. The dispute raises questions about revenue rights and legal recourse in indie collaborations, where a developer who created the entire game can be locked out of distribution accounts by a co-developer.
