The game engine is the foundation of your project. It decides which platforms you can reach, how good the game can look and how fast the team can work. The three engines we are asked about most are Unity, Unreal Engine and Godot.

Unity

Unity uses C# and is the most widely used engine for mobile games.

  • Excellent Android and iOS support and a huge asset store
  • Strong in 2D and stylised 3D, AR (AR Foundation) and serious games
  • Large talent pool and countless tutorials
  • Mature ad and in-app-purchase integrations

Best for: mobile casual and mid-core games, AR apps, educational and training games.

Unreal Engine

Unreal uses C++ plus the visual scripting system Blueprints.

  • Industry-leading high-end 3D graphics (Lumen lighting, Nanite geometry)
  • Cinematic and virtual-production tools
  • Free to use, with a revenue share only above a high revenue threshold
  • Heavier builds and higher hardware requirements

Best for: PC and console games, photorealistic 3D, architectural visualisation, VR simulations.

Godot

Godot is open source (MIT licence) and uses GDScript (Python-like) or C#.

  • No licence fees or revenue share – ever
  • Lightweight editor, very fast iteration
  • Excellent 2D workflow, solid 3D for simpler projects
  • Growing community, smaller asset ecosystem

Best for: 2D games, indie projects, prototypes, education and teams that value independence.

How to decide

Ask three questions:

  1. Which platforms first? Mobile points to Unity or Godot; PC/console with top graphics points to Unreal.
  2. What visual style? Stylised 2D or low-poly works everywhere; photorealism favours Unreal.
  3. What about the team and budget? Existing skills and licence costs matter over the lifetime of a game.

Web games

For browser games and advergames, lighter options such as Phaser or Three.js often beat full engines because they load instantly without installs.

We choose the engine in the concept phase based on these criteria – and build a small prototype to validate the choice before full production.
