OK, I don't play mods - just the original how the developers meant the game to be, thank you, Jolie.

Kelsey doesn't alter anything. He's just a new NPC - complete with voiceset (!), how own original portrait, and tons and tons of dialogue. I think he even has more dialogue than the original Bioware NPCs - interactions with every NPC and all. (Note: He's a human sorcerer. With the way BG2 implements the class, it's all but impossible for a sorcerer to be a horrible character, power wise.) Better yet, he doesn't require you to play a therapist.
And Kelsey's a sweet, sweet boy.
That might be true for other games but BG doesn't need mods unless you have a twisted sense of "good". That game was badass.
Heh, not if you play a female PC and want an actually well-rounded romantic interest. For that matter, there're tons of odds and ends Bioware never get around to fixing. (See Baldurdash fixes.) And then there's the fact that ToB is... less than adequate.
