Dominions 5 procedural content generation program. It allows you to make nation packs for nationgen games or create content for your mods.
Package includes two batch files (.exe analog): nationgen for creating nations and spritegen for making sprites.
Due to Necron being an asshole with many interests and catastrophic decline in natgen popularity in his comminity he is kinda delayed the project. For a person it would like there're no progress, but natgen-n has actually DEV versions, which are not full releases and marked as 'tags'. You still can download them as usual.
NationGen is originally made by Elmokki and Ealb, however project was abandoned since jan 2021. last version was 0.7.0-RC12, you can check it here: https://github.com/elmokki/nationgen
