My wonderfully brave and good party has now reached a reputation of 20, but Korgan still sticks with us. Has anyone actually had some party members leaving because of too high/low reputation ?

I haven't had that problem in BG2, happened in BG1. It will happen although I'm not sure what each characters breaking point is.

Korgon, edwin, victoria all leave at either 18 or 19, what you got going is pure sweetness, (unless you just reached, then he will take a day to decide to bail on ya.)

Minor correction to IronEagle --- there's no Victoria in the game but there is a Viconia. :D

Well at least i got the name close enough, so you knew who i meant. I could have called her "whats her name" but "Drow Lady" would have been better maybe?

Well I guess something's wrong with my game then. I have a rep of twenty for several game-weeks now (I'm in the underwater city)and Korgan still seems quite happy with my party -> me, neutral good Fighter, Minsc, Aerie, Jaheira and Imoen. I won't complain, coz Korgan is a great frontline fighter ;)
