* The Drengin AI in [[http://www.computerandvideogames.com/article.php?id=161570=pcg&skip=yes this]] ''VideoGame/GalacticCivilizations 2'' game seems to be utterly retarded. For example, it singlehandedly forces a galaxy wide peace treaty and then immediately declares war. It kills the ships defending a planet and then avoids taking it over. At the end of the game, it turned out the AI was performing ThePlan all along-- if the player's race had been eliminated, the ''Terrans'' would have immediately won a diplomatic victory. ''Every'' AI race knew this and manipulated the lone holdout to their advantage. Except the part where the player [[AscendToAHigherPlaneOfExistence researched immortality]] while everyone else did all this.
* In Twilight of the Arnor, why does the base Terran colony ship have a rotating ring with the colony modules on it? Simple - planets have gravity, and the easiest way to get gravity in space is to have things spin. The colonists are being kept from adapting to zero gravity so they take less time to get used to the new colony world! ...That and it looks cool.
* The biggest difference between major and minor civilizations in that unlike the former, they cannot be culture flipped regardless of how much influence another empire is having on them. However, this comes at the cost of them never expend their influence to other planets beyond their home world, even when given access to technology that enable them to do so. In ''VideoGame/GalacticCivilizations 3'', if you read the background history for the minor races on the diplomatic screen, they will all have a cultural/biological/political reason for never expanding. For example:
** [[AnarchyIsChaos The Marauders are a bunch of anarchical scavengers, and as such, don't have the centralized government structure needed to organize any form of expansion]];
** [[DescentIntoAddiction The entire Lantern species got addicted to euphoric vapors, and ended up having their entire society restructured around getting more of the drug]];
** [[BreakTheCutie The Klepart's first united technical achievement as a species was the creation of a great beacon tower to send a signal into space.... Which ended up summoning a group of slavers to raid their home world, collecting every child on the planet. With an entire generation lost, this crippled them demographically, as well as making them wary of ever doing anything space related again]];
** [[StrawNihilist The Odair are extreme nihilists who see no point at doing anything since the universe will succumbs to the eventual pull of entropy. As such, why ever even bother expanding into space anyway?]]
