Sid Meier's Civilization V: The 4X people still call the best

Firaxis released Sid Meier’s Civilization V on 21 September 2010, and the argument for it as the series’ high point has never really gone away, even with two newer mainline entries on the shelf since. Ask a long-time 4X player which Civilization to hand a newcomer and Civilization V, specifically with the Brave New World (2013) expansion installed, still comes up more than Civilization VI does. That’s worth taking seriously rather than dismissing as nostalgia, because Civilization V earned the reputation with two mechanical decisions that fixed real, longstanding problems in a series that traces its DNA back through Civilization II to Sid Meier’s original 1991 game.

The hex grid and the death of the stack of doom

Every Civilization before V used a square grid, and every square-grid Civilization eventually degenerated into the same tactical non-decision known across the community as the stack of doom: pile every unit you own onto a single tile, march it toward the enemy, and let the strongest unit in the stack absorb hits for everything behind it. It wasn’t really tactics. It was accounting — count your stack’s total strength against theirs and the outcome was largely decided before a single combat animation played.

Civilization V replaced the square grid with hexes and, more importantly, imposed a hard one-unit-per-tile rule. Suddenly a stack was impossible, and warfare became genuinely spatial: flanking bonuses rewarded surrounding an enemy unit, terrain choke points mattered because you could only push one unit through a mountain pass at a time, and ranged units needed melee escorts because a lone archer left undefended on open ground was just a free kill. It’s the single most important rule change the series has ever made to its own combat, and every Civilization since has kept it, because the alternative — the stack of doom — simply isn’t defensible once you’ve played a version of the game without it.

Brave New World and the victory type nobody else has matched

Civilization V shipped with two expansions, Gods & Kings (2012) and Brave New World (2013), and the second is the one that turned a good strategy game into the one people still measure sequels against. Brave New World reworked the Culture Victory around Tourism, a resource that spreads specifically to civilizations with lower Culture than your own, generated by Great Works — actual named artworks and artefacts your Great Artists and Great Writers produce, which you then have to physically house in museums and amphitheatres built to hold them, competing for wall space against rival civilizations racing to fill their own.

It’s a victory condition built on out-competing rivals for cultural relevance rather than simply accumulating a number, and no Civilization since has replicated it with the same texture — Civilization VI’s Culture Victory, built around tourists visiting your wonders and Seaside Resorts, is a reasonable system but a blunter one, missing the specific pleasure of watching a rival’s Tourism output stall because you’ve cornered the market on Renaissance-era Great Works. Brave New World also introduced ideologies — Freedom, Order, Autocracy — as a late-game branch that reshaped diplomacy around which bloc a civilization belonged to, adding a genuine Cold War flavour to the back half of a match that the base game’s tech tree never had on its own.

Gods & Kings and the religion nobody expected to matter

The first expansion, Gods & Kings, gets less credit than Brave New World, but it fixed a gap that had sat in every prior Civilization: religion existed as flavour, never as a system. Gods & Kings let a civilization found a religion via a Great Prophet, hand-pick beliefs from a list — some benefiting the founder, some benefiting anyone who adopts the faith, some rewarding pure spread — and then watched that religion compete with rivals’ faiths for converts city by city, missionary by missionary. A well-built religion could out-convert a neighbour’s state faith inside their own borders, turning what looked like a spiritual side quest into genuine soft power over an enemy’s population.

Gods & Kings also introduced espionage as a standing system rather than an occasional event, letting a civilization plant spies in rival cities to steal technology, rig elections in city-states, or simply gather intelligence on what an opponent was building. Neither system is as tightly wound as Brave New World’s Culture rework, and both show their age next to Civilization VI’s more integrated religious and espionage mechanics, but Gods & Kings is the expansion that proved Firaxis was willing to bolt entirely new systems onto a shipped game rather than just patching numbers — a pattern that Brave New World then took much further.

The AI that plays it straight

Civilization V’s AI has a reputation, deserved, for being less sophisticated than Civilization VI’s agenda-driven leaders — it doesn’t have hidden preferences or public agendas, and it can be predictable once you’ve learned its patterns. But that predictability cuts both ways. Civilization V’s AI plays a comparatively legible game: it declares war for reasons you can usually see coming (a border dispute, a denounced ally, a coveted resource), and it fights wars using the same hex-and-flank rules the player does, without the difficulty-slider production bonuses feeling as blatant as they do in some other strategy titles. Where Civilization VI’s leaders feel like characters with quirks, Civilization V’s feel like opponents playing the same ruleset you are, which is a smaller, more honest kind of AI design and one that ages better than a flashier system built on gimmicks the community can eventually reverse-engineer.

That legibility also makes Civilization V a genuinely good multiplayer game in a way few 4X titles manage. The hex-grid combat and the absence of hidden agenda mechanics mean human opponents can read each other’s positions the same way the AI reads them, and a Civilization V multiplayer match — slow as any Civilization match is — rewards the same tactical hex-reading that made the single-player combat click in the first place. Community-run multiplayer scenes built entire play cultures around this: Play By Cloud, Firaxis’s asynchronous turn system added specifically to let Civilization V matches run over days or weeks between busy players, kept dedicated multiplayer groups alive years after the game’s commercial shelf life would normally have ended, precisely because the combat model rewarded patient, readable decision-making rather than twitch reactions a slower turn cadence would otherwise punish.

Difficulty scaling in Civilization V also aged more honestly than its reputation suggests. The higher difficulty tiers hand the AI production and growth bonuses rather than pretending the computer plays a smarter tactical game, and Firaxis was upfront about this in developer commentary at the time — the AI’s actual combat and diplomatic decision trees don’t change between Prince and Deity, only its starting resources and yields do. That honesty means a player who masters the hex-and-flank combat system can beat any difficulty tier through tactics alone, which is a rarer thing in the genre than it should be; plenty of strategy games disguise a resource handicap as an intelligence upgrade and let the player assume they’re facing a smarter opponent when they’re really just facing a richer one.

What Civilization V is missing next to its own sequel

None of this is an argument that Civilization VI is worse. Civilization VI’s district system solves a real problem Civilization V never addressed — the flat, undifferentiated tile-improvement grid that made city planning a spreadsheet exercise rather than a spatial one — and the era and Eureka systems give Civilization VI’s tech tree a texture Civilization V’s linear queue doesn’t have. Playing the two back to back, Civilization VI’s opening fifty turns are the sharper, more mechanically alive experience.

What Civilization V has instead is coherence. Every system in Brave New World-era Civilization V — hexes, one-unit-per-tile, Culture-via-Tourism, ideologies — reinforces the same central idea that space and cultural relevance are the scarce resources an empire competes over, and none of it fights against another system for the player’s attention the way Civilization VI’s districts occasionally compete with its era score and loyalty pressure for the same turns. It’s a tighter, more finished-feeling game specifically because it does less, and does what it does without a seam showing.

Brave New World’s trade route rework deserves its own mention, because it quietly solved a problem the base game never addressed: the economy had no meaningful connective tissue between cities beyond raw production totals. Trade routes turned caravans and cargo ships into a physical thing moving across the map, visibly vulnerable to barbarians and enemy raiders, carrying either a gold bonus or a science and culture boost depending on whether the route ran to a foreign civilization or stayed domestic. A trade route to a rival wasn’t just income; it was a soft diplomatic tie that made war with that partner more expensive to declare, since severing the route cost both sides something real.

Civilization V remains available on PC and, via a later console port, on consoles, and it’s still one of the more approachable entry points into the Master of Orion II school of 4X design for a player who’s never tried the genre — a rare thing to be able to say about a game now a decade and a half old.

Spoilers below

The Brave New World Culture Victory’s actual finish line surprises first-timers: rather than accumulating toward a fixed score threshold, it plays out as a direct comparison against every other civilization’s Culture output. You win the moment your Tourism has exceeded every rival’s Culture, which means a runaway leader can be denied victory for dozens of turns by one small, culturally stubborn neighbour whose Culture keeps climbing just enough to stay out of reach. Diplomatic Victory, reworked in Brave New World around the World Congress, similarly rewards a slow accumulation of votes and delegates rather than a single decisive act, and a player who ignores city-state relationships for the whole game will find the mechanic essentially locked out by the point they notice it exists. Both victory types reward attention paid from turn one over effort spent scrambling in the final stretch — the single biggest structural lesson Brave New World has for anyone replaying it today.

The other endgame wrinkle worth knowing before a Brave New World campaign: an Ideology chosen too late can lock a civilization out of its strongest tenets, because the Freedom, Order, and Autocracy trees gate their best late-game bonuses behind total Ideology-point accumulation, and a civilization that switches ideology mid-game to chase a rival’s bloc loses accumulated progress rather than carrying it across. Committing early to an ideology that suits an empire’s actual playstyle, rather than the one a rival happens to have picked, avoids a scramble in the last third of the game that catches most first-time Brave New World players off guard.
