May be controversial, but one of the problems with the girls in this game, compared to AZL. is that they are "too easy"
One of the appeals of straight shota is that it starts off innocent and steadily progresses. In AZL, you had to talk to them and develop a relationship to even get them to see you in a sexual way at all. The relationships developed better, they were more sweet, there were more scenes. When the girls finally say "holy shit am I going to actually have sex with him?!" it's really hot. Fits the fetish more.
In this game, pretty much every girl is down to fuck almost immediately, with almost no brakes or misgivings. They're all just thirsty sluts. I like thirsty sluts, it just makes the interactions have less substance the quests are often short. The relationships aren't that interesting.
What do I mean by interesting?
When you had sex with the mom is AZL, she had all the guilt. the feeling of taboo, the hesitation. that you would expect from a mom...she was also very sweet. Gradually can't help herself,and things escalate slowly, and it generally fits the whole mom fetish more.
Its way more interesting and hot than "oh hey we found some porn! I'm totally okay with fucking my son now!" That ges for most girls in the game. Town of passion does this MUCH better. So it's not like this guy doesn't understand this. Maybe he didn't want to copy AZL too much?
I dunno, maybe I'm wrong.but that's how I feel.
