I agree with what you said about more pleasant personalities in BBAS than the original BB, but this time for Kira and Ann.
On another note, have you played the latest updates of Glamour? It's worth pointing out to Ann and Kira lovers (especially Kira lovers) that DS does give those two characters more credit in Glamour (playing as Max of course). Ann especially comes out as more human than in the original BB, where she was just this annoying post-traumatic snob who remained as psycho-rigid as before, even as she was fucking her own son for money and for pleasure.
So now it seems that Kira worshippers like me can switch from BBAS to Glamour while waiting for the updates for each game, and get some quality time with her as well as with Ann.
