Things weren't the same, that's why there are many fans of Revan story in SW, because it's not about good jedi and evil Emperor, but there's civil war and mind control and jedi purge in KOTOR2, and things did look a bit more archaic. It wasn't ancient SW, but an older SW, sabers with powerpacks happened even before all that.KoTor games had a good story, but they definitely fucked up the setting. The story was set 4000 years before the movies, yet everything looked exactly the same
Sure they could have gone even older, when jedi and sith fought with metal swords, but who would buy SW game without lightsabers?
The game which fucked everything was KOTOR Online, which ditched Revan and all the mysteries and just copypasted vanilla SW everywhere.
