Zg80 is a prequel to Metastases (2009).
A report by Human Rights Watch (then called Helsinki Watch) from 1986 described Yugoslavia as one of the most repressive communist countries in Europe.
According to the data of the World Bank, i.e. the World Development Report from 1989, the average inflation rate in Yugoslavia was as much as 57.2%. After 1986, inflation got completely out of control and exceeded 100% per year, and by 1990 it was 1000% per year. At the end of the 80's, prices first doubled every year, and eventually multiplied tenfold.
