* ArcFatigue: So you were expecting to experience the Battle of Naboo from the Gungans' perspective, and fight the battle droids straight away? Well, guess what: You'll have to complete ''three'' '''Old Republic-era''' missions set around Boss Nass' ancestor, Gallo, and the War of the Gungan Tribes first. The Gungan campaign has six missions, plus a seventh non-canon bonus mission. That means that ''half'' of the campaign is dedicated to this relatively unrelated war. It doesn't help that the hero that the campaign is named for is Boss ''Nass'' and not Gallo.
** The [[BearsAreBadNews bursas]] from the Gungans campaign. They are very fast, can tear down a building in mere seconds, and are just as deadly in combat.
** Jedi or Sith Masters in the standard game are an ordeal to fight. While they cost a considerable amount of nova crystals to produce, they have great speed, a large amount of hit points and armor, can regenerate those hit points if left alone, and dish out high damage to nearly all units (mechs in particular). Worst of all, they can [[EnemyExchangeProgram mind trick (convert, as in Age of Empires) your own units to their side]] [[note]]And unlike AgeOfEmpires monks, Jedi Masters, and even Knights, are quite durable [[/note]]. Certain techs even allow them to do this to certain buildings and heavy units, meaning that Assault Mech you had moving to attack the enemy is now firing at your own infantry lines, a Troop Center you built is now producing enemy units OR that Jedi Master of your own has [[FaceHeelTurn turned to the Dark Side]]. They even can gain stealth as well (though this is not quite as bad since [[UselessUsefulStealth the detection skill is surprisingly common]] but they still can jump you if you're not expecting it). The best way to deal with them are [[MageKiller Bounty Hunters]], who have an attack bonus against them but are otherwise impractical for pitched combat, and large massed groups of repeater infantry, who have [[BeamSpam a ton of blaster bolts]] and [[WeHaveReserves low unit value]], but even then, they can cause a great deal of problems.
** Most unique units can fit into this as well. Special mention goes to the [[EliteMooks Destroyer]] [[HeavilyArmoredMook Droid]], [[AttackItsWeakPoint T-47 Airspeeder]], [[TheBerserker Wookie Berserker]], [[LightningBruiser Royal Crusader]], and Geonosian Warrior [[DeathFromAbove (if you are a trooper or worker).]]
* HilariousInHindsight: The Wookiees are a playable faction, and this game was made ''before'' [[Film/RevengeOfTheSith 2005]].
* MostAnnoyingSound: Many, as SWGB is fairly weak in the sound effects department. Notable ones include:
** Selecting a group of Rebel tauntaun cavalry and having to listen to the same grunting.
** The error sound you hear every time you do something wrong (like trying to build a building you don't have enough resources for, or hitting the "Idle Worker" button without actually having idling workers).
** "GYAHAHAAAALLLLL!!!" (the obnoxiously loud and loudly obnoxious death screech of Naboo troopers)
** Most scenario specific troops have obnoxiously long and loud death sounds, and you'll usually find a ''lot'' of them. The Cloud City Security troops from the Imperial Campaign are of particular note, due to having a "budget WilhelmScream" as their death cry.
* TearJerker: The first Gungan mission has Boss Gallo finish hunting for Nerfs for his village...and then Bursas attack, and he (along with the player) is forced to watch helplessly as [[DoomedHometown Otoh Sancture]] [[WatchingTroyBurn is literally torn to pieces by the hulking beasts]], until Gallo is the only one left. Sure, Marsune gives him worker Glurgs to help him rebuild the village, but it's still very unsettling considering the implications of the loss of life that was experienced just prior.
* ViewerGenderConfusion: Mahwi Lihnn, the bounty hunter hero for the Trade Federation. Anyone that has read the novel ''Darth Maul: Shadow Hunter'' will know Mahwi is female. But in ''Galactic Battlegrounds'', she's voiced by Roger Jackson with a [[LarynxDissonance raspy voice]]. To an extent, there's also Excellency Lathe Parthenian, who is clearly meant to be female but she has the same icon as the male Hanoon soldiers.
