These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Star Wars: Galactic Battlegrounds
Arc Fatigue: 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 threeOld 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.
Demonic Spiders: The bursas from the Gungans campaign. They are very fast, can tear down a building in mere seconds, and are just as deadly in combat.
Most Annoying Sound: lots and lots; SWGB is fairly weak in the sound effects department. Selecting a group of Rebel tauntaun cavalry and having to listen to the same grunting sounds every time you give them a move order will drive you nuts — almost as bad as 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).
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.
