KotOR & KotOR: TSL, are RPG's, in so much as you play the role of a jedi. Being a jedi in these two game is central to the story. I would class it as more of a cinematic type of RPG, but make no mistake, it may be linear, it may only have two possible endings (maybe more for TSL's) but it IS an RPG, maybe not the type you are used to or were hoping for, but you still play the role of a certain character.
If you are looking for an open ended starwars RPG which lets you play as whatever you want, I'm afraid it aint either of these two, but keep your chin up because its bound to come out, its inevitable.
