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.

The OpenMW team is proud to announce the release of version 0.39.0! Grab it from our Downloads Page for all operating systems. This release brings background cell loading and caching, which is a feature not to be missed. Initial support for object shaders has found its way back into our engine, and a host of bugs have been smashed. See below for the full list of changes.

OpenMW is a free and open source project by fans of the Elder Scrolls 3: Morrowind. If you want to support one of our long term developers (4 years) at his patreon that would be greatly appreciated. The vanilla game and expansions are fully playable at this stage of development.

I love exploration in games! Morrowind is one great game that scratches that itch! I have long had the desire to make a game for housebound people that would allow them to feel like they are getting out. Perhaps this is the engine I have been looking for. With all original assets, I could do almost anything with OpenMW and make an original game. I have to learn OpenCS though. I never got into Morrowind modding due to the fact that it wasn't open source. Why spend time modding for a game with a limited shelf life? This changes things though in a big way. After all, because they released the source, people are still modding for the original Doom! But I never finish my creations anyway.

No pressure guys, but if you don't finish OpenMW, I will curl up in a fetal position and weep. :( Keep up the good work! You are doing an amazing job! I don't take lightly how much work has gone into this project!

ok what about this ideas?
Mount system for horses?(look at mount and blade,that is the best way i think)
vehicles like ships and horse carts? (i say vehicle for using them as extra inventory space not just mount them)
gibs (you know body parts go flying their separate ways after death)

are you going to add this things in the future?

how about split screen?

Reply Good karma Bad karma+4 votes

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

Reply Good karma Bad karma+1 vote

It may be too difficult to implement but I too would love splitsreen, lan and online multiplayer :D

Reply Good karma Bad karma+3 votes

serious sam game have a very good way for input devices,you can actually have 2 keyboards and 2 mouses,using 2 usb and 2 analog inputs at the same time.perfect for split screen or for 2 monitors in the same pc.
