i would prefer bg2 style romances, along with friendship path.
that would mean- 30+ talks that give TIME for any relationship to have actual depth. no mostly plot-related talks, or only-in-camp comments. i loved how npc's slowly developed over time, throuh many talks and additional mini plots. of course, i assume a more mature handling of the matter, above 12yo mark (no sex being the point of it all, no constant psychotherapy for companions etc.). on the similar note, i would prefer if romance would not be important for any bigger event, only showing few minor consequences, like bg2.
