OpenMW-CS vs Reloaded-II

OpenMW-CS is a free editor for making or changing mods and creating original games. Its editing tools cover files, world and mechanics data, characters, and assets, with record filters and a cell view. The editor supports plugin and script editing, mod packaging, and ESM, ESP, .omwgame, and .omwaddon formats. The project says OpenMW can run original games made with OpenMW-CS; those games do not require Morrowind. Playing Morrowind does require a legally owned copy, because OpenMW does not include its content or assets. Official releases are listed for Windows, macOS, and Linux, alongside distribution channels including Windows Chocolatey, Linux distribution repositories, and Flathub. The manual is intended as both an introduction and a reference, including for people familiar with Morrowind modding, but cautions that OpenMW-CS remains in development and the manual does not cover its shortcomings. Mods requiring MWSE, MGE XE, or MCP are incompatible because those tools modify the original Morrowind executable. The source code is released under the GNU General Public License version 3.

Reloaded-II is a free, modular framework for creating mods for x86 and x64 games. Mods can be written in .NET and C#, and native mods are also supported; the project says they can use libraries and NuGet packages while running in isolation. The loader includes dependency ordering, early hooks, hot reload, real-time console and file logging, and Visual Studio debugging and profiling support. Its launcher manages multiple games and per-game mod sets, with built-in configuration, automatic updates and a mod downloader that offers one-click downloads on supported websites. The automatic installer installs Reloaded-II and runtimes in one click; the documentation says this usually takes under 30 seconds. The project says it does not modify game files and can be removed by deleting its folder. Windows users are directed to the installer, while Linux users are directed to a setup guide. Listed platforms include Windows, Linux via Wine or Proton, and macOS via Wine. The FAQ advises against using Reloaded-II with multiplayer games because games with effective anti-cheat may ban users.
