Games Like Hearts of Iron IV - Mobilization Pack (DLC) Steam Key (2026)

Shared: Grand Strategy, DLC Expansion

Three distinct Legendary Lords, one massive free update, and a Slaanesh campaign that builds Pleasure Palaces and spends Decadence like a war economy. Tides of Torment is the strongest argument yet for staying in the Immortal Empires sandbox.

Shared: DLC Expansion

Sunset Harbor patches one of Cities: Skylines' longest-standing gaps - a working waterfront economy - and sneaks in the transport hub overhaul transit nerds have wanted since day one.

Two city-building giants bundled together: one lets you manage an Earth metropolis, the other challenges you to keep a Mars colony alive. Pick your planet.

Shared: Grand Strategy

Over a decade old and still the benchmark for grand-strategy depth, EU4 rewards patience with hundreds of hours of alternate-history sandboxing, but the DLC catalog demands a plan before you open your wallet.

Shared: Grand Strategy

Put 50 hours in before you see the cracks, and 500 before you stop caring about them. Stellaris is the deepest space grand strategy on PC, but the DLC wall and a shaky 4.0 patch make the entry point complicated right now.
