## What it is
Open 3D Engine (O3DE) is an Apache 2.0-licensed, multi-platform 3D game engine for building AAA games, cinema-quality 3D worlds, and high-fidelity simulations. It features the modular Atom renderer, a Gem-based extension system, visual scripting, and a full editor, with no fees or commercial obligations.

## Use cases
- build a AAA-quality 3D game without licensing fees
- create cinema-quality 3D worlds and visualizations
- develop high-fidelity simulations for robotics or education
- make a cross-platform game for Windows, Linux, and Android
- build a multiplayer game with a built-in networking stack
- extend an open-source game engine with custom modular Gems
- prototype gameplay with visual scripting instead of C++

## When to choose
- you want a fully open-source, royalty-free AAA-capable engine
- you need a physically based, modular renderer (Atom) with DirectX 12/Vulkan support
- you prefer C++ and CMake-based workflows with full engine source access
- you're building simulations or robotics projects alongside games
- you want modular feature selection via Gems rather than a monolithic engine

## When to avoid
- you need a lightweight 2D-only engine for simple games
- your team relies on macOS as a primary development platform (still experimental)
- you want a huge asset store ecosystem and turnkey tooling like commercial engines offer
- you cannot meet heavy build requirements (Visual Studio, CMake, 16+ GB RAM, 100+ GB disk)
