I am among those playing since Day 1 and who has not seen the City yet.
The endings keep on changing and Act III seems to be getting more and more buggy.
After several playthroughs of Act - with various combonations of Charatcers - I am starting to savour Act II.
I don't think I will venture into Act III before Patch VI.
BTW - I've not romanced anybody ever. Same as in BG1/2 :P - call me queer if you wish, but this element of the game leaves me cold.

Girls dig vampires? Now, that's news. Who'd had thunk that ... :P
Girls will be girls, boys will be boys, dey iz different dats all ...
