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.

I always imagined playing Morrowind with like 4 friends. This would be a dream come true. This was the best Elder Scrolls game second to only Daggerfall.

I am really excited about this. Morrowind isn't open-source, so you are essentially MAKING it open-source! There are so many open-source games, but most of them are first-person shooters. With Open MW, and now Arx Fatalis being open-source, that is changing. Not that I have anything against first person shooters, but I want variety, and I think of Morrowind as the king of RPGs.

Romans 6:23 "For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord."

We're first recreating the original game (v1.0), after that we'll be changing game mechanics ourselves (post v1.0). Because everyone has a different vision on mechanics, we're also hoping for a good modding community which shall do give the player a wide variety of game mechanics to chose from.

Love this. I can't wait to see what I'll be able to change. What's going on in regards to editing tools?

It's being worked on, but it's not progressing as fast as we would like to. We're planning on showing the editor as soon as it's presentable. In the meantime you can check out it's progression (and that of the engine) on this page:
