Best Tool by Game Dev Task
Game Logic & Systems
Cursor excels at writing game systems because it understands your entire project context. Feed it your component hierarchy and it generates matching scripts. For complex AI behavior trees, Cursor’s multi-file editing is unmatched.
Shader Programming
ChatGPT is surprisingly good at HLSL/GLSL shaders. Describe the visual effect you want and it generates working shader code. Claude handles shader math explanations better.
Networking & Multiplayer
Netcode is where AI tools struggle most. GitHub Copilot offers the best autocomplete for networking patterns, but always review carefully. Race conditions and synchronization bugs require human oversight.
Game Design Documents
Claude writes the best game design documents thanks to its long context window and superior writing quality. Upload your entire GDD and it maintains consistency across updates.
Recommended Setup for Game Developers
- IDE: Cursor ($20/mo) for daily coding with project-wide AI
- Quick answers: ChatGPT for shader code, algorithm explanations, and debugging
- Documentation: Claude for writing GDDs, technical docs, and reviewing large codebases
- Art assets: Midjourney for concept art and texture references
Frequently Asked Questions
Can AI write a complete game?
AI can generate individual systems and scripts, but designing a cohesive game requires human creativity and iteration. AI is best used as an accelerator, not a replacement for game design skills.
Which AI tool is best for Unity?
GitHub Copilot and Cursor both have excellent C# support. Copilot is cheaper ($10/mo), but Cursor’s project-wide context understanding gives it an edge for complex Unity projects.
Is Cursor worth double the price of Copilot for game dev?
For professional game developers, yes. Cursor’s multi-file editing and project context make it significantly more productive for game systems that span multiple scripts.
