Game Development with AI
Which AI Should You Choose for Game Development?
Choose GPT, Claude or Gemini for game development. Separate models, coding agents and game engines, then compare results using the same small prototype.

Choose a rule before choosing a tool
GPT, Claude and Gemini are model families. Codex, Claude Code and Gemini CLI are development tools that work with models. A game engine provides scenes, input and the running game. Start with a one-sentence rule: what does the player do, and when do they win?
Give each candidate the same prototype
Example brief: In the existing engine, build a single-screen game won by tapping three targets. Separate starting, playing, winning and restarting. Show the plan first, then changed files and checks actually run. Do not add accounts, a shop or a new engine.
Use the same project and engine version. Compare the completed loop and human corrections required rather than code length. This is a proposed evaluation, not a measured model ranking.

How to check the result
- Do winning and restarting actually work?
- Are engine version, language and plugins recorded?
- Was touch input tried on a real phone?
A code response is not a playable game
A project that cannot open in its engine is unfinished. Verify the small loop before expanding art, audio and level count. A model’s explanation cannot establish that players will understand or enjoy it.

Frequently asked questions
Is a powerful LLM enough to make a game?
No. You also need a suitable engine, clear rules, verified code and player observation. One model is not the best fit for every game and team.
