About Openmw

OpenMW is an open-source, open-world RPG game engine for playing The Elder Scrolls III: Morrowind, as published on GitHub. The project's listed version is 0.52.0 and it is released under the GPLv3 license. You must own a copy of Morrowind to play it through OpenMW. The project also includes OpenMW-CS, a replacement for Bethesda's Construction Set.

According to the project, the main quests in Morrowind, Tribunal and Bloodmoon can all be completed. Some side quest issues are expected but described as rare. The project lists known issues that must be resolved before a "1.0" release. Pre-existing Morrowind mods can be hit-and-miss, because OpenMW's script compiler checks for errors more strictly than Morrowind does.
