Larian posted some stats and it seems Larian themselves are suprised at how many people disliked Astarion, the most rejected character it seems.
I am like "gee, you make a mostly jerk character and then your suprised most people dislike him? color me suprised"
Most romanced Shadowheart (no brainer, she is the traditional beauty looking lady) or Gale (a suprise for me, but i imagine most of the female fanbase went for his good looks, since hes also firmly on the tradional beauty spectrum!)
Both of those characters were also the most "normal" ones in terms of content, personality and plot, so its no suprise there. They were also characters that you cannot miss in the story.
