This is Croatia - Hearts of Iron IV: Yugoslavia Rework Fan Made Remake

The Yugoslavia Overhaul mod completely changes the Yugoslavia gameplay through new events, decisions, a big focus tree, balance of power mechanics and a lot more. The mod also aims to depict a more realistic situation that Yugoslavia was in before and during World War 2. The mof also allows the player to break up Yugoslavia and play as Croatia which also has its own focus tree, events, decisions etc.
