I don't think it would have been nearly as successful or strong an experience without having KotoR prior to it. KotoR 2 is just a great deconstruction of all of that. It's a little cheesy and melodramatic at times with it all, but that's what Star Wars is.
It really does a fantastic job of capturing and mimicking that classic Star Wars feeling in this epic kind of journey from beginning to end. I think KotoR is the single best piece of Star Wars media that has delivered a similar feeling of awe and surprise that the OT provided.
