it shows you exact conflicts so you will never encounter a problem in game and wonder what it is caused by, because you have in-depth details of exactly which mod files are replaced by which mod.
It does Not overwrite main game files, all of the overwrites are done virtually.
it loads a lot faster than other mod managers.
it doesn't keep mods zip files inside the directory, only the extracted files, so your hard disk space is not kept hostage for duplicate files.
it is feature-rich, a lot of features that are missing from any other mod managers.
it supports a wide range of compressed files, not only zip or 7zip, but also.
it is open source and an active team is developing it, unlike Nexus mod manager which was abandoned for years, or Vortex that is new and Beta and needs years to eliminate bugs and problems in the program code.
it is Stable, not beta like Nexus mod manager or Vortex, they are both beta, but not MO2.
it does not modify game files or folder, so your game folder is kept clean, not a single file is written in there.
