* 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).]]
** Basic Training Campaign: Colonize Alaris Prime and train a militia to destroy an infestation of Gundarks--> Eliminate the Trade Federation presence on that moon.
** Gungans Campaign: Boss Gallo and Captain Marsune vs. Boss Rogoe in 3,000 BBY[[TimeSkip -->]] Boss Nass vs. Trade Federation forces in 32 BBY.
* HilariousInHindsight: The Wookiees are a playable faction, and this game was made ''before'' [[Film/RevengeOfTheSith 2005]].
* LethalJokeCharacter: [[EthnicScrappy The Gungans]] are an entire faction of this. Not only do their buildings repair automatically [[note]]Albeit slowly[[/note]], not only can they build prefab shelters underwater [[note]]Thus giving them access to more space in certain maps[[/note]], not only are their frigates stealthed [[note]]Albeit UselessUsefulStealth, since ''all'' frigates, regardless of faction, are stealth-detecting, but still[[/note]], ''not only are their medics able to heal more units than the medics of any other civilization,'' [[OverlyLongGag NOT ONLY DO THEIR TROOPERS HAVE GREATER RANGE THAN THOSE OF ANY OTHER CIVILIZATION]] [[note]]To the point where, depending on the enemy's limitations (or bad decisions), they can [[GameBreaker outrange fortresses and Assault Mechs]] [[/note]] but they have ''the'' most powerful Mechs and Heavy Weapons in the game, ''AND'' their elite unit is a mobile shield generator, thus giving their armies extra protection even inside enemy strongholds. A skilled Gungan player will make life hell for a non-Gungan enemy.
** Their awesomeness will be a ''little'' bit limited if the battle takes place on a non-aquatic map, but not by much.[[note]]And whatever you do, do NOT face a Gungan player when "All Techs" is selected. [[SchmuckBait Just don't]].[[/note]]
** [[EpilepticTrees Makes you wonder if the game's developers designed them this way]] [[TakeThatAudience intentionally....]]
* 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)
* NoKillLikeOverkill: Units spawned by cheat codes tend to be excessively brutal. [[KillerRabbit Simon the Killer Ewok]] is lightning fast, and has shields, regenerating health, and more firepower than a dozen repeater troopers. The Bongo Marauder is a boat unit with roughly the same stats and killing power. Clone Campaigns lets you summon a [[CoolStarship Victory-class Star Destroyer or a "Blockade Runner" Corellian Corvette]], both of which can flatten forests and deal more damage than a regular air cruiser. But the king of excess is easily the Death Star, which is slower than a drunk bantha and has the longest reload interval in the game, but has max health and shields, and can wipe literally everything off the screen in one shot, even normally invulnerable resource crystals and ''the terrain of the map itself'', leaving a featureless flat plain in its wake. You can also summon Decimators from the story mode, but they pale in comparison to the above units.
* RecycledScript: Several missions in ''Galactic Battlegrounds'' resemble missions seen in the campaigns of ''VideoGame/AgeOfEmpiresII''.
** The Basic Training campaign is played out more or less the same as the William Wallace tutorial campaign. This is especially noticeable in the first, sixth, and seventh missions.
** The second mission in the Gungan campaign has the player control a small group of soldiers that travels to different Gungan tribes with the intent to recruit them to join your cause, much like the first mission of the Genghis Khan campaign.
