Building Mobile Games in 2025: Unity vs Godot vs Custom Engines

The Great Engine Debate

After shipping dozens of mobile games, we've used nearly every major engine and framework available. Here's our honest assessment of the landscape in 2025.

Unity: The Industry Standard

Unity remains the go-to for most mobile game projects, and for good reason:

• Massive ecosystem of assets, plugins, and tools
• Cross-platform deployment to iOS, Android, console, and web from a single codebase
• Proven at scale — the majority of top-grossing mobile games run on Unity
• Strong AI/ML integration capabilities

The downsides? Unity's pricing model changes have made some indie developers nervous, and the engine can feel heavy for simpler 2D games.

Godot: The Rising Challenger

Godot has matured significantly and is now a serious contender:

• Completely free and open-source — no revenue sharing, no strings
• Lightweight — perfect for 2D games and simpler 3D projects
• GDScript is approachable for designers and junior developers
• Growing community and improving documentation

We've shipped two games on Godot this year and were impressed by the development speed for 2D projects.

Custom Engines: When Nothing Else Fits

For highly specific requirements (like our NovaQuest project), sometimes you need custom solutions built on top of frameworks like React Native Game Engine or custom WebGL renderers.

Our Recommendation

• AAA-quality 3D games: Unity, no question
• 2D games and indie projects: Godot is increasingly our first choice
• Hybrid app-games: React Native with custom game components
• Web-based games: Three.js or Phaser

The best engine is the one your team knows best and that fits your project's specific needs.
