Wastelands of Slavia(Development is frozen)

Slavia is a colony planet, which was founded by ardent Slavic pan-nationalists. They believed that if they found a suitable place for each nation, then finally the Slavs would be able to live in peace and achieve the perfection of "humanity ". Now ask any person or non-person, anyone will answer that it's bullshit, not an idea, but idealists don't give a fuck. Naturally, when people settled, different elites appeared, with different interests, who began to get what they wanted with diplomacy or weapons. Of course, conflict after conflict appeared more and more resentments, the planet began to divide more and more into regions fighting among themselves, and when less than 10% of the planet remained under the Central government of Slavia, the government decided to blow up everyone here and fly to another planet. And so they did. Several thousand nuclear missiles were fired overnight, hitting the entire planet. The regional authorities decided that their neighboring enemies were beating them and released everything they had. And voila. The once beautiful planet with mountains, rivers, plains and forests has become a fucking radiocatian wasteland. And you'll have to live here. Warning: The plot about pan-nationalists was a way to create a unique world where every Slavic culture exists and does not try to cause interethnic hatred.
