Well, that's an interesting topic. I would agree with @@Cerez regarding similarities between the tyrant orders, be it the Galactic Empire or the Sith Order of older times. Either the establishment, the existence or the affects were seen in the next several games: - Star Wars Rebellion (a major strategy with internal database. Showed both diplomacy and war used to conquer worlds. Search youtube for cutscenes, both victory and loss for either side (you will see the liberation of Imperial Coruscant, as well as the reprisals from he Empire, if you lose the final battle) - Force Commander (a strategy, showing both Rebels and Imperials and their attempt to seize the worlds. The videos from this game show the actual occupation of one alien world with their dwellers brutally massacred by stormtroopers) - Shadows of the Empire (just an alternative to show, that the Empire had other enemies as well, like Black Sun) - Dark Forces I (a very old game, I would recommend a mod for JA with the same name. Level 2 shows a city, ravaged by the Imperials, after they learnt that rebels were among the locals). - Dark Forces II (we see an occupied city of Barons He'd on Sulon, "Empire surely knows how to ruin a perfectly good city". The citizens are scared, attacked by thugs, while the Empire stays in a large tower in the centre of the capital, with ruined and abandoned quarters around). - Mysteries of the Sith (unlike its predecessors it shows an Imperial city of Katraasii spaceport with many citizens, while stormtroopers don't bother the locals too much) -Star Wars Galactic Battlegrounds (we see how the Empire deals with planets like forest Krant, asteroid colonies and others; we also see allies of the Empire, Reitha - the Imperial Agricultural world, attacked by Rebels, etc). However it is notable, that the games show the Empire the way we all perceived it back in 1990s. Today the image closer to the Force Unleashed prevails, which does't show any cities per se, more Imperial installations. There are also dozens of books. But it will take time to find proper description of the Imperial rule there. Though it might be useful if you need more details. During the KOTOR era the situation was a bit different: both the Republic and Sith Empire officially existed, while Rebels were in hiding mostly and almost no planets claimed their allegiance to the Rebels in open. Also the Sith seem to rely more on Sith ideals, while the Galactic Empire has their own Imperial philosophy, often omitting the fact, that they are ruled by the Sith. More that the Empire brought peace and security, as well as order to the Galaxy, ravaged by the weak Republic, corrupt Trade Federation and the Clone Wars with Jedi traitors. Notably, the Sith of the Malak Empire allowed local traditions to exist further - Taris had this one for instance.
