I would also like the so-called replay value explained. I played the game first time around as light. Loved the plot, loved the story line. But, when I saw there was only 4 places to go for the main quest, I was like "okay, this must be the first phase of the game. More worlds will surely open up after I find these 4 artifacts, or new areas of these worlds." Imagine my confounded chagrin when this was limited to a single, relatively smaller (and prior I would have thought this impossible), end world.
With the size and depth of modern games, I don't see how one could call KOTOR 1 anything but short. Especially considering it was an RPG. From my RPG experiences, I would expect a 4 part scavanger hunt to be perhaps one of about ten or more parts in a main story line. Granted, they managed to slow one down with sidequests, but even then I found it short. In fact, when I replayed the game for the darkside I found only one new area which I had previously missed. And it wasn't a big deal either, just a room I hadn't looked into. That's not replay value, IMO. Going to the same place, doing the same thing, just with a different undertone is NOT replay value. It's redundant. In the end, KOTOR 1 left me wishing they had, in fact, simply made Morrowind with lightsabers. Heck, Bethasda included a consumer-friendly editing program so you could make your own quick and easy mods to the game. Maybe someone could just take that and make a Star Wars conversion. Okay, I kid. But the point is, KOTOR 1 lacked any real depth. KOTOR 2 needs to be done so that the two force sides and other things actually alter your progression, making you do totally different things. Then you could go back and play another way and experience new places, people, events. Otherwise, I see no point in not uninstalling a game after it's finished. But that's just me.
