Choose based on project needs: Godot for 2D or open-source indie projects, Unity for cross-platform 3D or DOTS performance, and Unreal for AAA visuals with Nanite and Lumen. Consider team size, learning curve, and cost models like Unreal's 5% royalty after $1M.

Godot is excellent for 2D games, especially when open source matters, while Unity suits larger teams with bigger asset pipelines. Unreal has limited 2D support and is generally not recommended for 2D-focused projects.

Map abstract actions instead of physical buttons, since confirm and cancel buttons differ per platform. For example, confirm maps to A on Xbox, Cross on PlayStation, and B on Nintendo, keeping your input code platform-independent.

PlayStation requires TRC compliance, Xbox requires XR compliance, and Nintendo requires Lotcheck certification. Study these platform guidelines early in development to avoid rejection during the submission process.

Common bottlenecks include excessive draw calls, garbage collection spikes, complex physics colliders, and expensive shaders. Profile first using Unity Profiler, Godot's Debugger, or Unreal Insights, then apply batching, object pooling, or LOD shaders as needed.
