Developer GiantessGameUE5 immediately disputed the release, claiming it happened without permission and that they are pursuing legal action. The game, which lets players control a giant woman destroying a city or play as fleeing citizens, was originally distributed to Patreon supporters starting in 2022. A co-development arrangement with AGGRESSIVE MASTERY began around January 2025, and the Epic Games Store version entered Early Access on July 23, 2025. 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 writing, AGGRESSIVE MASTERY has not issued a public rebuttal, and the Steam store page remains active.","whyItMatters":"The dispute exposes a pattern where a developer who created the entire game can be locked out of distribution accounts by a co-developer, raising questions about revenue rights and legal recourse in indie collaborations.","webCardHtml":"\u003cp\u003eGIANTESS PLAYGROUND is a sandbox simulator built in Unreal Engine 5, featuring over 20 female characters and modes including Sandbox, Rampage, Hide-and-Seek, and Commander.

GiantessGameUE5 claims the trouble began when Micah approached them about using a destruction plugin, then later demanded higher usage fees and 50% of sales. They say most development work remained theirs while Micah handled publishing and revenue, with payments falling behind.
