## What it is
Duality is a modular, plugin-based 2D game development framework written entirely in C# and backed by OpenGL via OpenTK. It ships with a visual editor featuring live editing, asset and plugin hot-reloading, and a component-based design for building games.

## Use cases
- build a 2D game in C#
- open-source game engine with a visual editor
- component-based 2D game framework
- make a 2D game with hot-reloading editor
- extend a game engine via plugins
- prototype 2D games using .NET

## When to choose
- you want to develop 2D games in C#/.NET with a full visual editor
- you value a clean, extensible plugin architecture and component-based design
- you prefer an open-source engine with MIT licensing

## When to avoid
- you need 3D rendering capabilities
- you need a large ecosystem, asset store, or commercial support
- you primarily target non-Windows platforms, since editor builds are Windows-focused

## Facets
- artifact type: framework
- maturity: maintenance
- function: game-engine, graphics, plugin-system, gui
- domain: cross-platform
- platform: windows, cross-platform, dotnet
- tags: 2d, csharp, opengl, visual-editor, component-based, gamedev, game-development
