Yes, KoTOR is a good game, smooth and artificial, like SW movies (that's a bit of sarcasm, oh my) And it is worth playing, especially when no one else is going to release something of that caliber on the market. 2003 was dull.
Bioware was manufacturing RPGs for some time now and they have a good formulae -- a bit of this, a bit of that, turning everything upside down once per plot, and killing one evil guy in the end. As for me, i'd like to see something different from Obsidian, something with a fresh air in it.
