Top 10 Best 4X Games to Try in 2026

A 4X game asks you to explore, expand, exploit, and exterminate. Here are the 10 best games to try out this Steam Sale.

1. Age of Wonders 4

Best newer 4X you can finish without waiting on a roadmap. Triumph shipped it in May 2023. Steam is Very Positive, about 81 percent from roughly 23,000 reviews. You build a ruler, pick a culture, then bind tomes that add units, spells, and empire traits as the realm grows. On the campaign map you found cities, vassal free cities, and race rivals for magic materials. Combat is a separate hex battle: flanking, cover, and spell timing decide it, so an army is not a single strength number. A typical turn is scout, build, then resolve one fight you could have avoided. Later realm packs keep adding cultures. Skip it only if you want a historical setting.

2. Zephon

The 2024 combat 4X from the Gladius team. Steam is Very Positive, about 83 percent from about 1,900 reviews. Earth is already gone. You rebuild from a crater while alien parasites, machine cults, and human remnants share the map. Cities feed 11 resources. A tech web of more than 150 picks upgrades buildings and armies. There is no culture victory to hide in. A fight is positional: ranged units die if you walk them into the open, and late units punish a greedy expand. Players praise the tone and the stable multiplayer, and knock the faction count and some repetition. Buy it if Age of Wonders feels too bright.

3. Sins of a Solar Empire II

The real-time space 4X, out August 15, 2024, from Ironclad and Stardock. Steam is Very Positive, about 84 percent from roughly 8,800 reviews. You take planets, build orbital structures, and fight with fleets you can watch move, because the game does not pause for a turn order. Economy is logistics: metal, crystal, and credits have to reach the front, and a cut supply line stalls a push. Research unlocks hulls and empire abilities rather than a single doom stack. The September 2026 update and the Harbinger expansion added a fourth faction, the Eidolon. It is the pick if you want space and you do not want Stellaris's event pile.

4. Old World

Mohawk and Hooded Horse launched it on May 19, 2022. Steam is still Very Positive. Orders are a budget, not a free click on every unit, so a turn is which three things you can afford. Families scheme, heirs age, and a bad marriage can matter as much as a spear line. Ambitions give each leader a short goal, which is why a session ends in the classical world instead of crawling to factories. Combat is one unit per tile, with flanking and terrain. It is the history game to start if you like Civilization and never finish.

5. Endless Legend 2

Amplitude's sequel, in early access through 2026, with player reviews around 83 percent positive. Factions do not share a build order. On Saiadha, one empire might grow through minor-faction deals while another wants the map to break. Winter and cataclysm shifts change which tiles are worth holding, so an early city can become a liability. Armies are asymmetric, and the learning curve is the complaint in otherwise strong reviews. Early access means systems can move. Treat it as the fantasy experiment to play now, and keep Age of Wonders 4 if you want a finished ruleset.

6. Galactic Civilizations IV

Stardock's turn-based space 4X. The early access build landed in 2022 and 1.0 followed in October 2023. Steam is Mostly Positive, about 73 percent from roughly 2,500 reviews, under the games above it but clear of Mixed. You hit faster-than-light, survey planets, design hulls part by part, and push a readable galaxy map. Culture, alliances, and research are levers you set, not event chains you click through. A war is fleet position plus the colonies feeding it. Supernova filled in races and tools the launch build lacked. Choose it over Sins II if you want pauses between decisions.

7. Dune: Spice Wars

Shiro's real-time 4X on Arrakis, fully out in 2023, and Very Positive on Steam. You pick a house, expand sietches and villages, and fight over spice blows that relocate. The clock does not wait: harvesters have to land, fill, and leave before a sandworm or a raid takes them. Intelligence, Landsraad votes, and assassination sit next to army control, so a military lead can still lose the political window. Battles are smaller than Sins II and more about timing a push while your economy is exposed. It is the shorter real-time 4X if a full galaxy feels too big.

8. Terra Invicta

Pavonis's solar-system 4X, in early access since 2022 and still patched, with Very Positive Steam reviews. You run a faction on Earth first: countries, public opinion, and councilors who investigate, coup, or assassinate. Space opens once you can mine the Moon and Mars. A fleet is delta-v and armor, not a health bar, so a bad transfer orbit wastes a year. The pace is slow on purpose. Players who want a 90-minute empire should pick Old World. Players who want the alien war to feel like a program should start here.

9. Ozymandias

The short 4X, out in 2022, and Very Positive on Steam. A full match is a handful of turns on a small bronze-age map. You chain orders, plant a wonder, or wipe the neighbor before the board fills. There is no tech tree to drown in, and combat is a short exchange of units you already placed. It is the on-ramp if Age of Wonders still feels long, and it is not a replacement once you want cities that persist.

10. Total War: Warhammer III

Creative Assembly's 2022 fantasy empire game, and Very Positive on Steam from a far larger review pool than the rest of this list. The campaign map is the 4X layer: settlements, provinces, and legendary lords racing for a soul or a domination win. The battle is real-time, with flanking, spells, and artillery you place yourself. Immortal Empires is the mode that matters. You pick a race, expand a climate you can actually hold, and confederate or crush the neighbor. It is less of a pure turn-based 4X than Age of Wonders 4, and more of one than a straight tactics game. Buy it if the campaign map is the part you want and you do not mind a fight that plays out in real time.

Where to start

Fantasy battles: Age of Wonders 4. Grim fight, no culture win: Zephon. Real-time space: Sins of a Solar Empire II. A history game you can finish: Old World. Age of Wonders 4 wins a one-buy choice because the tome system changes the faction during the game and the review sample is much larger. Zephon wins if you want a dead Earth and no diplomacy victory. Skip Civilization VII and Ara until the Steam score leaves Mixed. Millennia is out too: Paradox shipped a final patch in October 2025 and stopped.
