The storyline of the entire series goes:
-Mysteries of the Sith
JO and JA never caught on... At that point, like I said, FPS gaming was moving away from how JO and JA were going, and as nice looking as they are (they hold up surprisingly well) they're just not as nice in how they control IMO. JK was kind of unmatched (and MOTS by default since it was basically the same engine).
It was the last innovative game ultimately... JO and JA didn't do anything new that other games weren't doing, and quite a few doing better.
I liked JA better, for some reason. The customizability of it I guess... It's a neat premise too, how the JA would function in basically the New Jedi Order and all. It kind of gave youa little hands-on with that concept that was really not touched in videogaming at all. That era was largely forgotten in anything other than comics and novels.
