OpenMW is a new and modern engine based on the one that runs the 2002 open-world RPG Morrowind. The engine (OpenMW) will come with its own editor (OpenMW-CS) which will allow the user to edit or create their own games. Both OpenMW-CS and OpenMW are written from scratch and aren’t made to support any third party programs the original Morrowind engine uses to improve its functionality.
