Tim Sweeney's recent public positioning splits across the engine business and platform policy. In an exclusive interview at Unreal Fest 2026, the Epic Games founder and engine lead Marcus Wassmer described Unreal Engine 6 as built around an open specification for interoperability, letting assets such as character cosmetics move between engines including Unity and Godot. The two compared the approach to web browsers sharing standards and confirmed AI integration through the Model Context Protocol, with no lock-in to any specific language model.

On July 1, Sweeney reopened the store-commission argument, posting that Steam's 30% base commission keeps major free-to-play titles such as Genshin Impact from launching there and that lower fees would attract those companies and raise Steam's revenue. Critics pointed to Epic's own layoffs and to the number of such games already on Steam.

Epic Games Japan has now set the keynote for Unreal Fest Tokyo 2026, scheduled for November 3 and 4 at the TFT Building West Hall in Ariake, Tokyo. Sweeney and Epic Games Japan representative Takayuki Kawasaki will share the keynote, covering the Epic ecosystem, the company's vision, and the rollout of UE6. More than 30 sessions are planned, and participation is free.
