Unlike typical grand strategy games, hardcore grand strategy games take planning and crank it up to 100, this time around giving a depth and level of customization that other RTS titles won’t even receive. However, just what are some of the most hardcore grand strategy games ever made?

10 Crusader Kings 3

Platforms: Windows, macOS, Linux

Whereas typical 4X titles take empire management to the level of civilizations, Crusader Kings 3 follows the tried and true Crusader Kings formula of running a dynasty instead. Straying away from usual empire domination tropes, CK3instead will have players take charge of a family’s rise to domination. What perhaps makes CK3 such a hardcore experience is its range of options, with choices such as religions, marriages, and even mere connections that can determine the survival of the player’s dynasty.

CK3 strikes appeal to most 4X crowds in how players can “game” the system to their advantage. Choosing and changing certain systems can tighten a family’s hold of its power. Wars can be started and ended on a whim, with conflicts arising from declaring one’s “right” to a territory - or even faking it. Even succession becomes a strategy, as players are allowed to start slow if it means setting up their character’s offspring to success.

9 Europa Universalis 4

Platforms: Windows, macOS, Linux

Players with a flair for the more historically-accurate settings might appreciate Europa Universalis 4 and its premise. Instead of starting an empire from scratch, players choose a pre-existing empire and become in charge of their affairs from the 15th century up to the point of Napoleon’s revolution. This puts players in charge of that nation’s successes, failures, and accomplishments throughout the Age of Reason.

Whereas other games have tight approaches to combat and simplistic approaches to socio-economic elements of their empires, Europa Universalis 4has a more complex take on politics, economics, and even conflict management. The game’s more authentic approach to replicating the happenings throughout the 15th century and beyond can make for an excellent alternate history 4K experience.

8 Stellaris

Platforms: Windows, OS X, Linux, PS4, Xbox One, Xbox Series X | S

Players with a love for sci-fi can look at Stellaris for a comprehensive space-faring 4X experience. Taking place around the invention of faster-than-light technology in the near future, players take the role of a species set to colonize the stars. Taking cues from other grand strategy games, Stellarisputs players in charge of managing their species’ economy and politics in the interest of achieving interstellar dominance.

However, unlike other 4X titles, victory conditions lie not just on what the players have declared. Rather, the ethics and governance of their chosen species can determine some other victory condition in every playthrough. Some species can forego galactic domination in favor of technological supremacy, resource dominance, or the destruction of all other life.

7 Total War: Warhammer 2

Platforms: Windows, Linus, MacOS

Fans of the Warhammer tabletop war game can finally take control of their favorite faction in a fight for domination - virtually! Total War: Warhammer 2 applies the critically acclaimed Total War formula to the Warhammer franchise, enabling players to command High Elves, Orks, and even Humans to wage war against each other. If players pursue the title’s story, Eye of the Vortex, each playable faction has its own campaign and storyline.

Gameplay-wise, Warhammer 2follows the Total War formula of engaging in diplomacy and political discussions before wartime. While players can move their armies across areas on the map, conflicts take place in real-time. As such, armies can plan their movements, change battle tactics, and exchange blows with the pleasant yet brutal violence signature to the franchise.

6 Distant Worlds: Universe

Platform: Windows

Players who loved Stellaris but want something more hardcore won’t get enough of Distant Worlds: Universe. At its core, Universe boasts a procedurally-generated galaxy of up to 1,400 star systems and up to 50,000 astrological bodies (e.g. planets, moons), giving players quite a lot of room to play with in their bid for galactic domination.

As a kicker, Universe boasts a unique automation system that allows players to be as attentive or as passive as they want with their experience. On the one hand, they can manually tinker with elements of their empire down to the last planet. Likewise, they can have automation handle everything else so players can cruise around with their ship. With Game Editor and exhaustive help systems, players can get quite the complete 4X space experience with Universe.

5 Endless Legend

Platform: Windows, macOS, Classic Mac OS

The world of Auriga is at the brink of destruction, and only one faction will be worthy enough to be its saving grace. In Endless Legend, players get a fantasy sci-fi treatment to the 4X experience. As with any typical grand strategy title, Endless Legend gives players control over their faction of choice as they slowly build their presence on the map. However, taking from the traditional RTS experience, each faction has both a dedicated backstory and unique ways to approach building their civilizations.

As such, players can enjoy quite a wonderful time approaching domination in different ways. Some factions can convert entire cities to their favor with spy units, while others specialize in perfecting trade and commerce. With stellar and fantastic art to complement the experience, Endless Legend is easily a visual and mechanical treat to 4X fans.

4 Sid Meier’s Alpha Centauri

Platform: Windows, macOS, Linux

Sid Meier’s Alpha Centauri is the Civilization answer to the sci-fi genre. Set in the galaxy of the star system of the same name, Alpha Centauri takes place in the 22nd Century, just after the United Nations has started a colonization mission to Chiron, a planet within the system. This takes place after the space victories in the Civilizationseries, but now players know that more troubles lie ahead. With an accident happening inside the UN’s Unity spacecraft, leaders on board form their respective factions and set out to conquer Chiron for themselves.

As with typical Civilization titles, Alpha Centauri approaches its gameplay from a development standpoint. Factions have to acquire land, gather resources, and do their respective research to slowly dominate against the rest. Now with ancient aliens and scientific technologies to check out, Alpha Centauri is easily a must-play 4X for fans.

3 Age Of Wonders: Planetfall

Platforms: Windows, PS4, Xbox One

Age Of Wonders: Planetfall is what happens when nations declare a race to supremacy after the fall of a galactic empire. In Planetfall, factions eye domination after the collapse of the Star Union, an intergalactic government ruled by humans. As such, factions have to explore the planet, oversee diplomatic relations, and even declare war to gather resources - all elements typical to 4X titles but in a more in-depth manner.

The game takes place in procedurally generated maps, with sectors divided into categories that could be allocated to energy, research, food, and production. As players expand their resources and land, so does their tech. It can come to a point that a faction can even research a Doomsday Weapon, a weapon of mass destruction that can make their factions much deadlier.

2 Civilization 6

Platforms: Windows, macOS, Linux, iOS, PS4, Xbox One, Nintendo Switch, Android

Civilization 6 is the most recent entry in the acclaimed Civilization franchise of grand strategy games, and it’s certainly the most in-depth at the time. As with other Civ titles, Civ 6stays true to the series premise of taking a Stone Age culture and seeing it evolve through the times. Players still need to acquire land and resources, as well as continuously develop their cities to ensure citizen happiness, cultural development, and pave the way for a more powerful empire.

As with other Civ titles, other nations also have rather advanced AI that allows them to make smarter decisions and more cunning actions throughout the gameplay experience. This is especially the case during trading, diplomacy, and wartime - three crucial aspects of Civ titles that often determine the intensity of a match.

1 Hearts Of Iron 4

Platforms: Windows, macOS, Linux

Who says 4X and grand strategy titles only take place in ancient history or the far future? Hearts Of Iron 4 is by far a 4X title as close to the modern world as possible, now taking place in World War 2. True to its setting, Hearts Of Iron 4 will have players choose any nation between 1936 and 1939, with the game documenting alternate courses of events taking place in this worldwide conflict. Outside scripted events, Hearts Of Iron 4 has quite a unique take on modern government systems, resource management, and wartime tactics during World War 2.

For instance, central to the gameplay are conflicts between nations. However, a lot of things also happen behind the scenes. Cities have certain building spots depending on their geography, while the nature of nations immediately affects how other nations interact with them. On top of that, technology can adjust military doctrines and unit approaches, making it quite a realistic reflection of the arms race between world powers at the time.
