Yup; I only have two planets left to go, plus the Yavin base. The conversations -- whether NPC to NPC or NPC to PC -- are fun and some are rather cute. Though, I imagine, male players don't find Carth's "whining" so enjoyable.
I've observed a trend -- at the KotOR official board, it seems that the general female players' consensus agrees that Bastilla is b-tchy; the male players think Carth is whiny. Eheheh. (Come to think of it, Bastilla doesn't seem to like a female PC much. I genuinely wonder why, considering that my PC is polite to her, and hasn't exactly slapped her around or something.)
