Terrible fucking argument, this IS a porno in VN form, as admitted by the creator of this fucking mod themselves. Too many pretentious dickweeds in Adult VNs trying to make this brand of entertainment something that it's not, couldn't hack it in the non-erotic entertainment industry so they try to make it in stuff like Adult VNs with their endless dialogue bullshit that ultimately leads nowhere.
Sex is the meat and potatoes of Adult VNs, the story and dialogue are important but only in the fact that they're supposed to ENHANCE the sex and the relationships with the characters you're fucking. What morons like yourself don't understand is that it's perfectly feasible for an Adult VN to have a great story without forgetting what it ultimately is, and frankly many Adult VNs are guilty of exactly that, forgetting what they are.
