I play Knights of the Old Republic over and over again first and foremost because it is fun.
I've played it good, evil, as I would make the choices (realistic!? ...if such a word has any meaning in a Star Wars game), as a man, a woman, a Zabrak (mods can be fun). I've tried to make friends with all the NPCs, to make enemies of all the NPCs, to recruit a large party, to kill off as many party members as I can...
...just play with it to see what it can do. And I must admit, I'm pretty impressed with it. I think Knights of the Old Republic is better than The Sith Lords because it can be played good or evil. Even when I play The Sith Lords as a good guy, it still "feels" dark somehow. I can't explain it any better than that; it's just a feeling.
