Yes, you're right. For "passive" medias, like movies and books, a unjustified long plot is boring. But, haha, that's the good about games. The game can be as long as you want to be. Some people go through Kotor in a week, but some others just finish it on a month or more!
So, what I want to say is that, the secret about the game being longer is investing on side quests and plots. But there're some examples of very good games that could make you play the same story forever and still have patience to level up, Like Final Fantasy XII
