it's just a matter of how you play, there are many different choices you can make and things you can do durring the game, it took me about 4 times beating the game(2 dark, 2 light) to find out everything. jackal probably has done the same
Actually I've beaten both games so many times over the years I've worn out every face available for your character in the game, even the female...just a few times though, wanted to see how things played out as cannically the Exile was female darkside
But to the Boogieman there's not much I can tell you, just go through the games and keep adapting with it as you go...do every quest you can, keep earning credits to buy new weapons and armor, just play the game! One thing I can tell you is keep talking to your companions, as you progress their stories will unfold before you...other than that when I first started playing these games and I got stuck (which was only a few times) I consulted gamefaqs.com, their walkthroughs saved my ass...so try using one there if you want to experience everything you can...
I'll be here if you need help...and take your time, Kotor III won't be out for a long, long, time...probley 2 years from now or so...take it easy bud
