## What it is
Amazon Lumberyard is a free AAA game engine with full source, deeply integrated with AWS and Twitch. It is no longer offered; the repository is archived and its community-maintained successor is Open 3D Engine (O3DE).

## Use cases
- build a 3d game with a full-source aaa engine
- study the source code of a discontinued game engine
- migrate a lumberyard project to open 3d engine
- create multiplayer games with aws and twitch integration

## When to choose
- you need to reference or maintain legacy Lumberyard source code
- you want to study how a AAA engine was architected

## When to avoid
- you are starting a new game project - use O3DE instead
- you need an actively maintained engine with support
- you cannot accept the restrictive AWS Customer Agreement license

## Facets
- artifact type: framework
- maturity: abandoned
- function: game-engine, graphics, simulation
- domain: cross-platform
- platform: windows, cpp, cross-platform
- tags: aaa-games, aws-integration, twitch, discontinued, open3d-engine-successor, game-development
