## What it is
OpenMW is an open-source, cross-platform game engine that reimplements the Morrowind engine, allowing players to run The Elder Scrolls III: Morrowind (with its expansions) using their own game files. It also includes OpenMW-CS, an open-source replacement for Bethesda's Construction Set for creating and editing game content.

## Use cases
- play morrowind on linux or mac
- open source replacement for morrowind engine
- improved graphics and ui for morrowind
- create mods with an alternative construction set
- run morrowind without the original engine
- play morrowind with widescreen and modern resolutions

## When to choose
- you own Morrowind and want a modern, open-source engine with better graphics, UI, and cross-platform support
- you want to develop or edit game content with OpenMW-CS instead of the aging Construction Set
- you want to play Morrowind on Linux or macOS natively

## When to avoid
- you want to play Skyrim, Oblivion, or other Bethesda games - OpenMW only supports Morrowind
- you rely on mods that depend on original engine bugs or quirky behavior, which may not work in OpenMW
- you need a general-purpose engine for building your own games from scratch
