Dragon Quest 8's sexualization of the only female party member (who apparently is underage, though I don't know if the game ever mentions her age).
This aspect of DQ8 actually made me uncomfortable on my recent playthrough (which I haven't finished yet). It, fortunately, is not present in DQ9, which also gives female characters more agency, and lets you play with an all female party if you so choose.
(DQ5, another game in the series that a lot of people really like, has the issue of a lack of female agency when compared to DQ4, but at least I don't remember it sexualizes anyone, aside from forcing the main character (who mus be male, unlike in DQ3 and DQ4) into a straight marriage.)
