NCF – Extended list of Neutral creatures.

The NCF installer for Book installs files not where you specify, but where it wants to. This is inconvenient, especially when you have some GOG version.
After I moved the files to the correct location, the game started. I haven't checked the creatures yet.
I'll keep you updated.

Psatkha, do you even check what you're doing?

I attack neutral creatures. Some kind of modified knight-horses. These half-wits (I can't call them anything else) instead of attacking me, encourage each other. Well, and they die from Plague, naturally. Who came up with the idea to give them Encouragement? It's free in terms of mana, of course, and the AI will use it instead of attacking.
