This page describes what the document states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability may vary by jurisdiction. Methodology
This is the legal agreement you accept when you download or use Unreal Engine, Epic's 3D game and content creation software. The most important thing to know is that while the engine is free for many users, if your product earns more than $1,000,000 in gross revenue, you owe Epic a 5% royalty on that revenue, and if you use the engine for commercial projects without distributing games to the public, you may need to pay per-seat subscription fees for each developer. You should check whether your use qualifies for the personal, indie, educational, or non-commercial exceptions before assuming you owe nothing to Epic.
This document is the Unreal Engine End User License Agreement (EULA) governing Epic Games' grant of rights to use, modify, and distribute Unreal Engine and related Licensed Technology, with legal basis as a contractual license rather than a sale of software. The agreement states that users may use the Licensed Technology privately without fees under certain conditions, but the terms authorize Epic to require either seat subscription fees (for non-royalty commercial use) or royalty payments at 5% of gross revenue exceeding $1,000,000 USD per product for royalty-bearing distributions, and the agreement expressly prohibits using Licensed Technology as training input for Generative AI Programs. The class-action waiver and jury trial waiver provisions are notable in their scope, and the agreement asserts broad audit rights over licensee records including bank statements; the royalty threshold and seat subscription exceptions for indie developers (under $1M annual revenue) and educational institutions are operationally significant carve-outs that narrow the practical burden on smaller users relative to large commercial studios. The agreement engages GDPR, CCPA, and related data protection frameworks through its privacy provisions, and the royalty reporting obligations and audit rights may engage financial compliance considerations; the AI training prohibition interacts with emerging regulatory frameworks around AI and intellectual property, though enforcement context for such prohibitions remains unsettled. Jurisdiction is governed by North Carolina law for US users and Irish law for non-US users, with mandatory venue in those respective courts.
