Epic Games Accused of Exploiting Programming Language Costs
15 Nov
Summary
- JavaScript is much slower than C++, limiting mini-games
- Major game engines have unique programming language choices
- Allowing certain languages means including or excluding popular games

According to a tweet from @xx_wired_xx on 2025-11-15, the user has accused @TimSweeneyEpic of Epic Games of using the creation of variable operating costs through programming language choices to justify variable charges. The user argues that the language itself is not impacting Epic's bottom line, and questions the justifications behind these decisions.
The tweet further explains that since JavaScript is much slower than C++, allowing its use would mean that mini-games would not be able to compete with native apps. The user points out that as major game engines and ecosystems have each made unique programming language choices, a decision about which languages to allow, such as Luau, Verse, C#, and GDScript, effectively determines whether to include or exclude popular games like Roblox, Fortnite, Unity, and Godot.
This suggests that the programming language debate is not just a technical issue, but one that has significant implications for the inclusion or exclusion of major players in the gaming industry. The tweet raises concerns about the potential exploitation of programming language costs and its impact on the competitive landscape for mini-games and larger game engines.
