## What it is
Amethyst is a data-oriented, data-driven game engine written in Rust, built around a massively parallel Entity Component System (Specs). Development has been halted; the team moved on to a fresh project, and it requires Rust 1.47 to compile.

## Use cases
- build a 2D or 3D game in Rust
- learn ECS architecture in Rust
- prototype games with data-driven prefabs
- write a multithreaded game engine application
- study a Rust game engine codebase

## When to choose
- you need a Rust engine pinned to Rust 1.47 for legacy projects
- you want to study a parallel ECS design
- you're maintaining an existing Amethyst game

## When to avoid
- starting a new game project - development is halted
- you need modern Rust toolchain support
- you need active community maintenance or updates

## Facets
- artifact type: framework
- maturity: abandoned
- function: game-engine, graphics, simulation
- domain: graphics, cross-platform
- platform: rust, cross-platform, windows
- tags: ecs, specs, data-oriented, gamedev, ron, discontinued, game-development, linux, macos
