Most of the people at Obsidian learned that lesson a few years ago.
The people at Lucasarts learned it a few years ago, and then forgot it after Jedi Knight: Dark Forces 2.
Huh? Inform me what I missed with JK: DF 2, perhaps I'll want to go explore the disk now that you've perked my interest. Did they cut endings out of JK 2, and JK: JA as well?
More on topic though, give it two or three years for development of KotoR 3 with a new engine and make it for Xbox Next/Xbox 2.
Well, JK:DF2 was the most advanced FPS at the time and it had a good story.
More importantly, however, the cutscenes were made using real, live actors instead of computer graphics. It'd probably be impossible to do something like that these days without taking out character customization, but it would produce higher-quality cutscenes and probably give KotOR 3 (if there is one) a more theatrical feel.
I remember being quite disappointed when I learned that the cutscenes in JO were made using the engine. KotOR's engine pulls it off much better, but still, it would be nice if they just stuck us with a character with a set name and use real actors. It would probably be a lot more expensive (which is why LA won't do it), but we'd have less black screens and more slim, mucus-covered lips pressed against each other in the cargo hold.
