Try to guess 20 first level administrative subdivision capitals (both in Croatia and other countries) closest to Požega (capital of Požeško-slavonska županija in Croatia).
For practical reasons, I'll make some exceptions:
For Slovenia and Northern Macedonia, only largest citiy in every statistical region is included.
For Luxembourg, Liechtenstein, San Marino and Andorra, only country capital and largest municipality seat are included.
If some subdivision capitals should be included, but are missing, please let me know in the comments.
If speakers of languages that don't use latin script consider I should include different transliteration of some city names, please let me know.
