Spec score 7.7 #12 of 26 in Game Mod Loaders

What it is

MWSE adds scripting capabilities to The Elder Scrolls III: Morrowind beyond those provided by the game's Construction Set. It gives mod authors ways to add features or behavior that would otherwise be impractical or impossible. From version 2.1, modifications can use Lua for event-driven behavior, with hooks for events such as level-ups, collisions and world activations. MWSE exposes APIs through Lua 5.1, with extensions from Lua 5.2 and Lua 5.3. Mods are not sandboxed, so they can include packaged Lua modules and native code. Included patches raise the mod limit from 256 to 1024, and crash dumps and logs help diagnose mod problems. MWSE is free software under the GNU General Public License and comes with no warranty. It supports Windows and Linux through Wine. Installation requires the x86 Visual Studio 2022 Redistributable, Morrowind Code Patch and Morrowind Graphic Extender XE. MGE XE bundles MWSE-Update.exe, which downloads the latest automated build. The project directs scripting advice and discussion to the Morrowind Modding Community Discord.
