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.

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