This report looks at 3 groups of game engines–from the industry leaders tosmaller open-source projects Key Game Engines Covered in the Report State of Game Engines Over half of the games released in 2024 were made in Unity, but only 26% ofthe units sold as Unreal Engine and custom AAA engines dominate large games Overview of Game Engine Popularity on Steam in 2024 Number of Games Releasedin 2024byGame Engine Commentary: •Unityis still the dominant game engine in termsof sheer volume of games being released onSteam•However, in terms of actual units sold, bothcustom in-house enginesas well asUnrealEnginebeat Unity in 2024•Godot, RPG Maker, GameMakerand othersimilar public engines count for just over 10% ofall games released, but barely 2% of the actualunits sold on Steam Smaller games still skew heavily towards Unity while larger end of the marketgets increasingly dominated by custom game engines Game Engine Mix by Size of Games Commentary: •Smaller games, especially indie titles, are morelikely to be built in Unity. Godot andGameMaker also do relatively well in that space.•Notably, Unity and Unreal Engine have strongpresence in every size category of games.•Larger game studios have built their internalengines for over ten years and still continue torely on them heavily. Unity has been the preferred choice by over 50% of games made on Steamsince 2021, but Unreal Engine, Godot and GameMaker have gained share Game Engine Market Share on Steam Over Time-# of Games Released Commentary: •Over 70% of games released in 2012 were made with custom engines–this has declined to only 13% by 2024•Unreal Engine keeps winning market share year by year while Unity has seen a slight decline since 2021•Godot and GameMaker have also grown in the recent years, albeit mostly among smaller games In terms of units, custom engines still dominate, however, Unreal Engine 5 hashad a very strong 2024 with more and more studios opting for UE5 instead Game Engine Market Share on Steam Over Time-# of Units Sold Commentary: •Custom game engines have been losing share year by year, with less than half of the units sold in 2024 coming from custom engines•Unity and Unreal Engine had almost equal market shares up to Covid; Unity saw a big jump in 2020, but hasn’t grown significantly since•Unreal Engine lost share in 2020 as major Unrealprojectswere delayed during Covid and teams were preparing for UE5 to launch•Ever since UE5, Unreal Engine has won back its lost share, culminatingina very strong 2024 (some of the biggest games of that year werebuilt in Unreal Engine, such as Black Myth: Wukong) VGI estimates that custom engines will continue to be swapped for UnrealEngine while Unity struggles to capture additional share Game Engine Market Shares on Steam, 2020, 2024 and Estimated 2030 It does not always make sense to switch away from an in-house game engine,but there are many cases where a third-party engine can be beneficial Rationales for and Against Moving Away From Custom Engines + Positives of a Public Engine -Negatives of a Public Engine •Immediate start–For a new studio, being able to start on“day one” rather than having to build your own engine isa huge advantage•Known quality–Engines like UE with Nanite and Lumenare proven quality in terms of performance and graphicalfidelity unlike a new in-house engine•No in-house maintenance–Much cheaper thanmaintaining a custom engine of a similar quality•Talent pool & training–Access to talent from othercompanies who already know how to use a version of theengine. Public engines also have a tonne ofdocumentation and training materials that don’t alwaysexist for in-house engines •Price increases–Market dominance allows a few enginesto dictate pricing•Customization requirement–Many projects st
