"Just one more turn" is the phrase many utter when they play Sid Meier's Civilization, a series beloved by many for its accessible yet complex game systems. Players work towards becoming the most renowned Civilization in existence, using technology, culture, wonders, or pure manpower to become the best.

Every Civ game released has come with at least one expansion pack, a large DLC adding new content and mechanics into the already rich experience. Most are welcome additions to the game, but few have missed the mark entirely. Here are the most noteworthy expansions created for Civilization, for better or worse.

10 Best: Civilization VI: Rise and Fall

As to be expected, Civilization VI: Rise and Fall expands on the already excellent systems players would come to expect from a Civilization title. This expansion focuses on adding Great and Dark Ages into the game.

Loyalty and ages were the high points of this expansion, making both great and bad times in your civilization equally engaging. Along with some general gameplay improvements, Rise and Fall was when Civ VI began to rise as a true sequel to Civ V. Make sure to buy Gathering Storm instead, however, as that expansion comes with all but the new civilizations introduced in this expansion.

9 Worst: Civilization IV: Warlords

There are so few bad expansions that the Civilization series has seen it is hard to pick just five of them. Warlords is a great addition to the already fantastic Civilization IV, but it does not cut it compared to Beyond the Sword,

Vassal States, new leader traits, new units, and all-new civilizations were introduced in Warlords. Each addition here was well made and expanded on systems in meaningful ways, but the number of additions made here remain lacking when compared to future expansions in the Civilization franchise.

8 Best: Civilization V: Brave New World

Brave New World was when Civilization V was started to be taken seriously as a sequel to Civ IV. Besides the scenario packs and extra civilizations released before, Gods and Kings just did not add enough to the table compared to what Beyond the Sword did.

That is an unfair comparison, however, as Gods and Kings was the first major expansion and Beyond the Sword was Civ IV's second. Regardless, Brave New World added culture victories, tourism, expanded on the already amazing religion system Gods and Kings laid out, and added the elegant yet effective social policies system, effectively adding skill trees to government ideologies. This is the most accessible and addictive Civilization has ever been.

7 Worst: Civilization: Beyond Earth: Rising Tide

Besides hybrid units, Rising Tide was a glorified aquatic unit expansion. New units are available to play, new biomes were added, and... that's it.

Really! An expansion called Rising Tide has nothing to do with climate change or environmental gameplay systems, which Firaxis would later add with Civilization 6: Gathering Storm. This game already lacked much of what made Alpha Centauri great, but this expansion did not even try to live up to the game it is obviously inspired by. It's just wasted potential of what could have been a great sci-fi game.

6 Best: Civ II: Fantastic Worlds

Civ II is not a typo. After Sid Meier departed MicroProse to create Firaxis, the Civilization name was unusable due to legal disputes. Regardless, MicroProse managed to create a rather unique expansion to an already great game.

Incorporating notable IP's includingbut not limited to, X-Com and Master of OrionFantastic Worlds added many scenarios that ranged from high fantasy to far in the future. A scenario editor was also included, allowing players to change virtually anything they wanted. This is no doubt when modding started to become synonymous with the Civilization series.

5 Worst: Civilization IV: Colonization

Technically Colonization is not an expansion to Civ IV but rather a conversion. This expand alone title revolves around becoming independent from your mother country.

The gameplay loop is typical of what Civ players would expect, finding land to create cities and managing a large civilization. Differences come in how your mother country sends troops to stop your independence and colonization of new land. This is not a bad game, but it does not add anything memorable or, arguably, fun to the series. It is fun for a few sessions but gets old quickly compared to the game it is based on.

4 Best: Civilization III: Conquests

Fans complained during Civilization III's lifespan that it did not live up to Alpha Centauri, lacking the additions that game made. Play the World did not help, being one of the buggiest expansions ever released by Firaxis.

Hailed for being Play the World but good, Conquests fixes issues brought from that expansion while adding some unique features. New governments were added, alongside the typical civilizations. Moreover, this expansion brought meaningful scenarios, bite-sized games in special periods of history that take significantly less time to complete than a full Civ game—a godsend for the now fixed multiplayer. This expansion added things that all future games included, and the fixes to Play the Game showed how amazing multiplayer Civilization truly is.

3 Worst: Civilization II: Conflicts in Civilization

Scenarios were the focal point of this expansion, adding 20 new ones for players to enjoy. The typical addition of units, technology, and music are all bundled like you would expect.

Besides that, a scenario editor was also included to let players create custom scenarios to play. Conflicts in Civilization was sparse for additions compared to what the series has achieved since then, lacking mechanical innovations that future games have seen. The scenarios themselves were great, but that is practically all you were getting with this expansion.

2 Best: Civilization IV: Beyond the Sword

Beyond the Sword is Civilization cranked up to 11. The number of additions made improved so many things it would take an entire list just to cover them all. Meaningful innovations were further supported with general game improvements as well.

Corporations, advanced starts, natural disasters, expanded victory conditions, AI improvements, new game types, random events, and even espionage are all included, and that's not even everything. This is the best version of Civilization that exists and can be further tweaked through fantastic community mods and extensive options from the game itself. This expansion is a must-play for any Civ fan.

1 Worst: Civilization III: Play the World

Play the World is the only Civilization expansion that is objectively bad. While all expansions bring additions and try to innovate, Play the World was playing catchup with Civ II, and doing a terrible job at that.

Multiplayer was the major innovation here, adding turn-based and real-time rounds into the game that could be used simultaneously. Unfortunately, this addition was so buggy that it made multiplayer games unplayable, plagued with actions being out of sync for other players. It also lacked a scenario editor that was acclaimed from Civ II, rather introducing lackluster game modes. It wasn't until Conquests came out that Civ III was taken seriously as a Civilization game.
