Engine selection and platform-specific principles.
1. Engine Selection
Decision Tree
What are you building?
│
├── 2D Game
│ ├── Open source important? → Godot
│ └── Large team/assets? → Unity
│
├── 3D Game
│ ├── AAA visual quality? → Unreal
│ ├── Cross-platform priority? → Unity
│ └── Indie/open source? → Godot 4
│
└── Specific Needs
├── DOTS performance? → Unity
├── Nanite/Lumen? → Unreal
└── Lightweight? → Godot

3. Controller Support
Input Abstraction
Map ACTIONS, not buttons:
- "confirm" → A (Xbox), Cross (PS), B (Nintendo)
- "cancel" → B (Xbox), Circle (PS), A (Nintendo)

5. Engine-Specific Principles
Unity 6
- DOTS for performance-critical systems
- Burst compiler for hot paths
- Addressables for asset streaming
Godot 4
- GDScript for rapid iteration
- C# for complex logic
- Signals for decoupling
Unreal 5
- Blueprint for designers
- C++ for performance
- Nanite for high-poly environments
- Lumen for dynamic lighting
6. Anti-Patterns
| ❌ Don't |
✅ Do |
| Choose engine by hype |
Choose by project needs |
| Ignore platform guidelines |
Study certification requirements |
| Hardcode input buttons |
Abstract to actions |
| Skip profiling |
Profile early and often |
Remember: Engine is a tool. Master the principles, then adapt to any engine.
