Arhg, when the Rebels were sitting around talking about how their spies got them the Death Star plans it was on Yavin IV, not Alderaan. Alderaan was a pile of space debris by then. Seriously, get it right!
Anyways, I never played this game but I know about most of the stuff that happened. I did however love the last the game in the Jedi Knight trilogy, Jedi Academy and to this day it is the game to play for authentic jedi action (not no stupid Force Unleashed).
