OpenMW is an open-source open-world RPG game engine that supports playing Morrowind.
OpenMW reimplements the Morrowind engine from scratch, allowing players to experience the original game with modern improvements while requiring ownership of the original Morrowind files. The engine handles the core gameplay systems, graphics rendering, and scripting that powered the original game. Alongside the main engine, the project provides OpenMW-CS, a replacement for Bethesda's Construction Set, enabling users to create and modify content for the engine.
The tool suits players seeking to replay Morrowind with enhanced graphics and user interfaces on modern systems, as well as modders who want to create new content or modify existing mods. The main quests across Morrowind, Tribunal, and Bloodmoon are completable, though some side quest issues may occur. Prospective users should be aware that modifications created for the original Morrowind engine may not run in OpenMW due to stricter error-checking in the script compiler and the engine's refusal to replicate certain quirky behaviors or bugs that some mods depend on. Mod compatibility is evaluated case-by-case, with workarounds implemented where feasible or mod fixes required otherwise.
The team maintains organized contribution pathways, including detailed bug reporting guidelines and a wiki documenting which mods work or fail under the engine. Community channels including forums, IRC, and Discord remain active for user support and discussion.
