I don't agree with you there Domi. Both KotORs, the Fallouts and Bloodlines did not have a large amount of fedex. As I recall, fedex are typical for the more actionpacked RPGs: NWN, IWD and so on, which may be the reason why I don't like those titles.
I only played KOTOR1 from all these listed, and it is an enjoyable game, but really, very linear. IIRC only NPCs sidequests are actually optional. Taris is about as boring as any other game's prologue with running around gathering items for quest givers; some of the planets are excrutiatingly fed-exy (*cough* Tatooine *cough*)
