Modora

Paradox games load mods in an order that matters, and a collection of forty mods gives you no hint about what that order should be.

The usual approach is a forum thread and manual reordering, which still ends in a crash on launch when two mods overwrite the same file.

Modora reads a public Steam collection, resolves dependencies and known conflicts, and emits a mod order you can import straight into the launcher.

Conflicts are shown rather than resolved silently, so you can see which two mods disagree over a file and decide which one wins.

A forty-mod collection becomes a working load order in about ten seconds, and conflicting mods are listed by name before the game is launched.
