MWSE vs Starfield Script Extender

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.

Starfield Script Extender (SFSE) adds scripting capabilities and other functionality to Starfield on Windows. It supports only the latest Starfield version available through Steam; the Windows Store and Game Pass editions are excluded. The official site lists build 0.2.21 for Starfield version 1.16.244. SFSE supports plugin loading by injection, with a plugin manager, a Scaleform menu plugin interface and preliminary support for custom Papyrus native functions listed in its changelog. Updates to Starfield have sometimes required plugins to be recompiled or their compatibility data changed. Installation uses Steam or the installer, followed by copying the DLL and EXE files into the Starfield folder rather than its Data folder. The game must then start through sfse_loader.exe. SFSE components use a code signature intended to reduce virus-scanner false positives. The software is free, with a listed plan price of free.
