Commercial strategy games and historical simulation

Why set a Democratic Japan challenge instead of fighting a conventional Hearts of Iron IV war?

The run teaches the game's political and national-management systems before multiplayer. That differs from adapting simulations to construct historical scenarios and draw data.

The Democratic Japan run is practice for understanding the game's systems before a competitive multiplayer match. That purpose differs from adapting games and simulations to construct particular historical scenarios and draw data from them. Crusader Kings III, Victoria 3, and Hearts of Iron IV abstract political and operational command in different ways, and a Hearts of Iron IV run need not reenact the Second World War. Avoiding constant warfare makes it possible to learn how the political economy and national-management systems behave. Commercial game practice remains separate from historical evidence, although adapted simulations can serve as structured research tools.
