In the name of the Tsar – Russian Empire triumphs in the First World War
This mod challenges the standard outcome, proposing a Russia that emerges victorious after a decisive breakthrough in 1916 suppressing Austria-Hungary, with Germany exiting the war. The postwar world then presents fresh challenges and diplomatic tensions to manage.

Formable Nations – create your own factions
While Hearts of Iron IV allows selecting any 1936-state, this mod lets players forge a new nation with custom traits, focuses, and priorities, along with its own strengths and weaknesses.
Old World Blues – strategy in the Fallout universe
Named after the Fallout installment, this mod places players in a post‑apocalyptic North America, controlling factions from the New California Republic to super mutants. It emphasizes nation-building, diplomacy, and warfare tailored to the Fallout lore.

A grand scale modification that places major houses such as the Lannisters, Targaryens, and Starks in a dynamic power struggle. Alliances shift, nations pursue their own agendas, and each dynasty has distinct traits and national focuses.
Equestria at War – My Little Pony war saga
A lighthearted, popular mod set in the My Little Pony world where factions clash in Equestria. Players can lead a faction, negotiate peace through diplomacy, or pursue conquest depending on their style.
Easybuff – a suite of cheats
For players who want faster access to Easter eggs or easier experimentation, this mod enables cheats with a single keystroke rather than manual code entry.
Customizations can extend beyond mechanics, letting the action jump to modern times, the distant past, or the near future. They also enable campaigns across Middle-earth, Westeros, and Azeroth, offering hundreds of hours of real-time play. It’s a compelling option for fans awaiting a future Hearts of Iron IV release.
