[[caption-width-right:330:Gnome vs. Goblin. Spot the difference.]]

In real-time strategy games, usually those in which the different sides represent wildly different cultures or even different species, there will often be colour-coded sub-factions that are said to be different in terms of composition, outlook or somesuch, but in actual practice there is no difference except the visual one.

Sometimes a form of GameplayAndStorySegregation.

Subtrope of PaletteSwap. See CosmeticallyDifferentSides, when it's applied to more than a select few units, and UndergroundMonkey, when [[SortingAlgorithmOfEvil the later versions are stronger, but not when compared to the heroes]]. Not to be confused with [[CivilRightsMovement Separate But Equal]].


[[AC: VideoGames]]
* In ''VideoGame/AgeOfEmpiresCastleSiege'', there are different civilizations, but ultimately all use the same soldiers and have the same upgrades. The only gameplay difference is that you get the associated earliest hero and the cultural unit just when you build the respect buildings and without need of pennons.
* In ''VideoGame/WarcraftII'', the manual contained quite a bit of background information on the setting, including blurbs about the different human nations and orcish clans and their differences. For example, the nation of Stromgarde is said to have an especially strong martial culture, but when they appear in the single-player campaign the only difference from the standard Alliance is that their faction colour is red rather than blue. Similarily, Alterac is orange Alliance and Dalaran is purple Alliance, and so on. Subverted in that some of their [=AIs=] and starting structures had differences. Dalaran, the magocracy, had especially many mage towers and the orcish Dragonmaw Clan attacked solely with dragons.
* Averted in the campaigns of ''Videogame/WarcraftIII''. The Blackrock clan which appears in two missions has a ''Warcraft II'' tech tree, and when the blood elves break off from the Human Alliance, the human footman is replaced by an elven footman (identical stats), and the basic ranged unit is an elven archer (functionally equivalent to the standard rifleman); the rest of dwarven and human unit positions are filled by [[spoiler: Naga]] units that are quite different from the units they replaced. Also, [[spoiler: Admiral Proudmoore]] has aquatic-themed units in the expansion.
* Also present in ''VideoGame/{{Starcraft}}'' in the expansion when an expeditionary force from Earth shows up and has units identical to those of the original Terran faction, who are descended from exiled criminals and had been cut off from all contact with Earth for several centuries. The new faction is the in-story [[HandWave justification]] for several new Terran units, and [[AllThereInTheManual the manual]] states that the UED has been spying on the local factions for generations.
** That being said Starcraft does at least feature three races that are quite distinct.
** Blizzard in the early planning stages wanted to have a separate UED faction but they didn't want an even number of campaigns, so they made the UED use Terran units and still have only three campaigns.
* In the ''VideoGame/CommandAndConquerRedAlertSeries'', during multiplayer games one can choose to play as different countries within the alliances that constitute the two sides. Though the units are basically the same, there are some small differences in terms of unit cost, construction time, armour values and so on. In ''Red Alert 2'' each sub-faction also has a unique special unit only they can build.
* In ''VideoGame/CompanyOfHeroes'' the last mission has the Americans working with a team of Canadians to defeat the Germans, yet the Canadian forces are identical to the Americans except for the fact that their units are designated as green. This is made even more obvious when the expansion pack has Canadian forces that are exactly the same as the British soldiers except that when you click on them they say something in a stereotypical Canadian accent (rather than an English or Scottish one). This only really applies to the Canadians, though.
* The background story of ''VideoGame/TotalAnnihilation'' is that the ARM and CORE are flesh and blood humans versus people that have transferred their minds into computers, and that this ideological conflict is the casus belli of the entire game. You wouldn't know it from the units employed in the actual game, since both sides are composed entirely of identical-looking hordes of utterly disposable machines.
** Ditto for ''VideoGame/SupremeCommander''; while the units look distinct from one another depending on their faction, and there are some mild differences in firepower and mobility (Aeon have the best early-game navy, UEF the best tanks, etc.), along with a few unique units for each one, they're more or less functionally identical and all play similarly.
*** Somewhat averted in the ''VideoGame/SupremeCommander'' expansion ''Forged Alliance'' where a 4th faction is introduced and all the other factions are given extra units. These tend to accentuate the differences in the factions more, although basic strategies still remain the same (go over there and stomp on that player).
** The manual for ''Total Annihilation'' gave some blurb about how the CORE (the computer side) copied the data of their best soldiers into all their units and the ARM (the human side) responded by developing a very regimented cloning and training-from-birth program to create ideal soldiers to pilot all their units. In other words, by fighting the war for so long they almost completely converged in their methodology, despite their differing ideologies. I'm sure there's an Aesop buried in there.
** While true for the most part, the few race differences there are are some of the best units. Core's light armor doesn't have a chance against Arm light armor, and Arm heavy tanks can't hope to win against a similar number of Core superheavy ones - which the Arm side lacks. Also, there are a few standalone units like the Arm Fido, a fast guerilla bot, and the Spider, a unit that has no offensive power but is great for stealing enemy units. Oh, and the [[HumongousMecha Krogoth]].
* In the ''TabletopGame/{{Warhammer 40000}}'' universe, each of the major Space Marine chapters is supposed to have its own unique specialized field, with equipment and tactics to match (and some even having different organizational structures). However, in the ''VideoGame/DawnOfWar'' computer games, the only differences are the Chapter colors and banner. This is only apparent on single-map battles or in multiplayer, however, as during the single-player campaigns only one Chapter (the BloodRavens) is actually present.
* ''VideoGame/WorldInConflict'' has three distinctive factions (the US, NATO, and USSR) which all use their respective vehicles. In game, they are all pretty much identical, with the exception of several offensive special abilities, one tactical aid and the heavy artillery unit.
* ''VideoGame/AgeOfEmpires'' has consistently moved away from this trope.
** The first game had everyone draw from the same tech tree, but each civilization had units it couldn't use, and bonuses to some of those it did.
** The second game added unique units for each civilization (Japanese Samurai, British Longbowmen), and the differences got larger - especially for the Maya and Aztec civilizations, who (obviously) lacked any form of cavalry or gunpowder units.
** The European civilizations in the third game zigzagged - some units, like Musketeers, Hussars, and most of the siege units, were shared among most factions. Others, like Strelets, Organ Guns, and almost all the units in the Ottoman arsenal, were unique to one faction. A few, such as Dragoons, Horse Archers, or Pikemen were limited to a few factions.
** The Native Americans in the Warchiefs expansion made a major break with this trope, with unique tech trees. They did share a few gameplay elements, such as the Fire Pit.
** The Asians were even more of a break, with virtually no shared units or technologies.
* ''VideoGame/AgeOfMythology'' played with this one - all factions had unique military tech trees and myth units, but shared many economic buildings and almost all non-mythological technologies.
* ''VideoGame/GrandTheftAutoSanAndreas''. The Grove Street OGS hate the palette-swapped Ballas. The only real difference between the two crews is the Ballas sell cocaine; otherwise both are filled to the brim with violent psychotics.
** Similar goes for the two Latino gangs in San Andreas.
** The Ballas in the south near the beach differ in that they are armed with pistols at best.
* VideoGame/{{Homeworld}}'s Kushan and Taiidan forces are pretty much palette-swapped units with different designs, but plays exactly the same way save for one unique unit each. Fighters defeat bombers, bombers attack cap ships, [[TacticalRockPaperScissors etc]] Justified in-story, as most of the advances along the tech tree are either back-engineered from captured enemy vessels or something new being thrown at you and your R&D guys coming up with a version of your own.
** Homeworld 2 however, pulls an aversion. While some ship roles between Hiigaran and Vaygr units are analogous (i.e. Destroyers are still front-line capital ships), design differences and unit behavior means that everything, including fighting strategy is completely different. For example, while Hiigaran fighters and corvettes are invariably weak against frigates, one Vaygr corvette type is designed specifically as a frigate killer, and amassed enough (very easy due to Vaygr's DeathOfAThousandCuts doctrine), they will sink destroyers in short order.
** ''[[MissionPackSequel Cataclysm]]'' also averted the trope rather thoroughly; instead of bombers for attacking capital ships, your fighters were modified to carry a couple of torpedoes under the fuselage. Corvettes (renamed gunships in ''Homeworld 2'') were... Well, that's kind of complicated. Capital ships were restricted to the support role until well into the mid-game, when you finally gained access to the [[BeamSpam Multi-Beam Frigate]] and the Destroyer.
* Present in ''VideoGame/RiseOfNations''; every nation has an identical tech tree and units except for certain special unique units and a set of bonuses.
* In the same vein as ''Team Fortress 2'', the Red and Blue Droid Armies in ''VideoGame/{{Awesomenauts}}.''
* The single-player campaign in ''VideoGame/BrutalLegend'' has Ironheade and Lionwhyte's army; their units are exactly the same, except that Lionwhyte's troops are glammed-up. [[JustifiedTrope Justified,]] as that portion of the game is a civil war and Ironheade is composed almost entirely of defectors from Lionwhyte's side.
* Aside from the {{Elite Mook}}s, ''{{VideoGame/inFAMOUS}}'s three factions all generally use the same strategies and weaponry, just with differences in uniform. [[{{VideoGame/inFAMOUS2}} The sequel]] is a little better about this trope, giving the three different factions different fighting styles.
