OpenMW is a new and modern engine based on the one that runs the 2002 Game of the Year, The Elder Scrolls 3: Morrowind. The engine (OpenMW) will come with its own editor (OpenCS) which will allow the user to edit or create their own games. Both OpenCS en OpenMW are written from scratch and aren't made to support any third party programs the original Morrowind engine used to improve its functionality.
To give you a better idea of what this project is about, here are some of the aims for the future of the OpenMW engine:

  • Be a full-featured reimplementation of the Morrowind engine
  • Run natively on Windows, Linux and MacOS X.
  • Support all existing content, including Tribunal, Bloodmoon and all user created mods (in case they don't use external programs).
  • Allow much greater modability: change game rules, create new spell effects, etc through scripting.
  • Fix system design bugs, like save-game “doubling” problem.
  • Improve the interface and journal system.
  • Improved graphics by taking advantage of more modern hardware.
  • Support to improve game mechanics, physics, combat and AI. (
  • (Possibly) Support to implement multiplayer.

NOTE: Playing Morrowind with this engine still requires one to own the Morrowind data files.

OpenCS will support the editing of for all OpenMW features. We aim for the editor to stay fully up-to-date with the corresponding OpenMW version, allowing the user to edit any newly implemented feature. It will also support editor plugins, files that add to the engine code which can extend the editor's functionality and allow it to be used as a debugging tool for OpenMW content. The OpenCS is not based on the editing tool which came with the original Morrowind game, it is a program made by modders for modders.
Important properties of the OpenCS are:

  • non-blocking
  • multi-threaded
  • multi-document support
  • multi-view support
  • high scalability
  • customisable GUI

OpenMW/OpenCS is released under the GNU General Public License version 3.

About OpenMW with 9 comments by OpenMW on Sep 18th, 2014

The OpenMW team is proud to announce the release of version 0.32.0! Grab it from our Downloads Page for all operating systems. This is one of the more magical OpenMW releases, bringing the completed implementation of all magic effects as well as NPC AI for casting spells, using potions, etc. in combat. The implementation of mouth movement, eye blinking, and several other NPC AI features breathe more life into NPCs in this release as well. Over 100 issues have been fixed in this release, as we steamroll towards 1.0! The tiresome affairs of real life have prevented our beloved WeirdSexy from creating a video for this release. We wish him the best in everything, and have our fingers crossed that he will work his magic for a 1.0 release video when the time comes! We are looking for someone to take over his role. If you love the Elder Scrolls and like recording videos please introduce yourself and show us a sample of your work on this forum there has even been an outline for a basic video script. It would be a huge help!

Correct me if I'm wrong, but open means open. As in you can literally make anything, and not a hackey version like you can in the regular games. Like turn the games into RTS MMO FPS' if you really feel like it.

That's true. To be able to add features you have to have a good understanding of the code though. That is why the OpenMW team will try to keep the code as easily understandable and hackable as possible.
