OpenMw mod for Morrowind

OpenMW is an attempt to reimplement the popular role playing game Morrowind. It aims to be a fully playable, open source implementation of the game. You must own Morrowind to use OpenMW.
To give you a better idea of what this project is about, here are some of the aims for the future of OpenMW:

• be a full featured reimplementation of Morrowind
• run natively on Windows, Linux and MacOS X
• support all existing content, including Tribunal, Bloodmoon and all user created mods
• allow much greater modability: change game rules, create new spell effects, etc through scripting.
• fix system design bugs, like the "dirty" GMST entries in mods, and the savegame "doubling" problem
• improve the interface and journal system
• (possibly) improve game mechanics, physics, combat and AI
• (possibly) support multiplayer at some point
• (possibly) improve graphics to use more modern hardware

OpenMW is released under the GNU General Public License version 3. It is written in the D programming language, and all source code has been written completely from scratch. It also builds on various other open source tools, most notably OGRE for graphics.
