Well now, Timmy, I don't think those are good ideas.
First off, RPG's based off books are horrid, simply because in an RPG, I want to create and play my own character, not be forced into playing a character somebody else made (in the case of Drizzt, a rather lame character, IMO). I know that you didn't explicitly mention Drizzt as an RPG character, but nonetheless, I'd heartily disapprove of any game that had him as a main character. Even in non-RPG's, I like a bit of freedom.
Anyway, I'm not sure how much I'd be looking forward to KOTOR 2, considering that I haven't played the first one. At the very least I'll be looking at whatever they make with a bit of interest, feigned or otherwise.
