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.

Split screen is not hard to implement, but LAN, online is hard to make.

I get 0x000007b whenever i try to start any of the files of openMW or CS(win64). 0.35RC.

Also putting recent version in downloads won't hurt. Just as copying installation instructions to readme.txt instead of links.

rly Oo arent there no license problems or some copyrights things that would stop that from happening? He cant just take your hardworked code and do a fully commercial super rpg XD

The RPG is theirs. An engine is an engine. People make games with Ogre3D all the time, and this is a step on top of that.

As for any IP complications with Morrowind, an entirely new game file can be created that doesn't use any part of Morrowind at all. :)
