Well, eroticism can be subjective, but I have no doubt in my mind that Dragon's Crown draws parallels with art not unlike Conan the Barbarian. Whether or not that appeals to an individual is irreverent. The game is very specifically drawn as erotic fantasy, heavily inspired by Nordic and European medieval art.
Like, I just don't get how people could look at someone like the Amazon and go "hurr fourteen year old boob fantasy". She's classically Amazonian eroticism: beautiful visage, gorgeous thick blonde locks, traditional curvaceous female anatomy, contrasted by an almost grotesque muscular physique of rippling abs, toned buttocks, and engorged thighs.
If that seems juvenile to someone, whatever. They're entitled to think that. I see medieval erotic fantasy, and an artist who knows exactly how to draw it.
