Game Engines arenaGame Engines
Game engines and real-time 3D frameworks, from full-editor incumbents (Unity, Unreal) through the open-source challenger (Godot) to the npm-installable web runtimes (three.js, Babylon.js, PlayCanvas, Phaser) and Rust's code-first ECS (Bevy). Judged on the classic axes — rendering, scripting, editor tooling, asset pipeline, platform export — plus the ones the AI era added: headless/CI builds and scriptable editors as agent surfaces, MCP servers (official versus community), LLM copilots, codegen-friendly APIs, and licensing trust — Unity's 2023 runtime-fee episode and 2024 cancellation are part of the record, cited honestly, as is Unreal's 5%-over-$1M royalty and Godot's MIT license.
