There are already many mods that are simply better than the mediocre campaign of the second game.
I think the Haven 1 campaign is an example of awfulness, a prime example of how not to make games, but even I have to admit that there are many, very many mods that are worse than it, because the ineptitude of people knows no bounds. If we remember that there are not so many mods for Haven 2 itself (about 600 compared to 4500 for the first part), then according to your words, it turns out that almost any creation is better than the campaign of the second Haven.
More dialogues, but they are (not all) unnecessarily drawn out, or simply boring.
The Storms campaign is the worst, followed by Underworld, then Mask of the Betrayer, and then Ordeals.
Where do we end up when we save the world?
