yeah u r right, it would have made KOTOR much better if u continued to play it after the "end".
But I don't think KOTOR & GTA are to similar, because GTA is all "dark side" with no "light side story"
Would have been cool if there were more undercover missions as in GTA, or maybe more in depth missions like if u could train the Rakatan Luo into a Padawan...
Is that possible??
