Kottor 1 > Kottor 2.
Don't get me wrong, they are both great RPGs...but, the first one had, you know, closure to it, at the end. Were as the second's ending was, "

thats it?" I liked the fact you could train one of your party members to be a Jedi...to bad I didn't find out till after I beat the game...Then I didn't really wanna go back a play it again because the ending pissed me off.
