They vary from Imperial bases to Jabba the Hutt's spaceship, so there is an enormous variety in locations to run around as well as enemies to battle.
Storm Troopers are fairly standard fare -complete laser fodder -but there are other more challenging
adversaries including Gamorrian guards who are armed with choppers -easy to kill from a distance but
fatal if they get too close -and pink aliens like Ree Yees that just hurl grenades around. Needless to say, you can't use the same tactics with these enemies as you might do with a Storm Trooper.
One thing you don't get the opportunity to do is battle it out with any of the established characters. Old favourites like Darth Vader and Boba Fett do turn up in the attractive cut sequences between each mission, but you aren't going to get to shoot it out with them in case you kill any surviving characters and the continuity is spoilt.
