Engine selection after Unity pricing reset

In September 2023 Unity announced a Runtime Fee tied to installs and revenue thresholds, then revised the plan after widespread developer pushback. In September 2024 Unity stated it would remove the Runtime Fee for games and real time 3D services built with Unity, returning to a subscription plus seat model for the current generation of the editor, subject to the terms Unity publishes at the time you license the software.

Epic’s Unreal Engine remains a strong competitor for high fidelity projects, with revenue sharing terms that kick in above defined gross thresholds as described in Epic’s public license pages. Godot and other open source tools also attract teams that want minimal license friction for specific genres.

Engine choice is no longer only a technical decision. Legal and finance teams review export control rules, source access needs, console certification support, and vendor stability. A mid size studio may keep two engine pipelines for different product lines simply to avoid single vendor concentration.

Migration costs are real: rebuilding tooling, retraining staff, and revalidating console ports can slip schedules by quarters. That is why many producers document exit criteria before they commit to a new major version upgrade.

The durable takeaway is to treat engine licensing like any other infrastructure contract: read the current terms, model cost under realistic shipping scenarios, and keep a technical spike budget before you lock art direction.
