I honestly think the game should have been called: "A song of cheating freaks" XD Everybody's creepy, dishonest or dumb in this town. Even (especially?) Mr Creepycop. Everything about that character screams "FAKE!", starting by his appearance.
As I said the MC is so dumb and careless I think it would be a good idea for him to jump from a bridge, the sister is a turbofreak that could be arrested for sexual harassment (because even men can be be "not in the mood" and feel uncomfortable sometimes) ; I'd love to kick her out of the house for good since her presence doesn't help the girlfriend condition at all - quite the opposite actually.
There's also no way that rapist Adrian could walk freely in town, since it would be totally possible for the police to find evidences of his action(s).
As a man, in real life, with a certain view on love, romantic relationships and loyalty (some would say "traditionalist"), I'm not even mad toward the NTR bullshit (I was really mad because of the very first scene) but I'm terribly embarassed by how fucking dumb the situations can be or evolve.
If I had to compare with another erotic game, Good Girl Gone Bad has a much more intelligent writing and the situations, even if some of them can be a bit extreme (example: turboslut Ashley ending in a latino gang), they're most of the time brought with intelligence, or don't feel out of place. The same way, the characters' reactions are logical or plausible.
GFA has good points, but for christ sake it's so dumb I can't take it seriously and can't feel what I'm supposed to feel. I don't really care about the characters because of that. Which is a shame.
Again, if I go back to GGGB (considering I mainly follow the Good Ash route), I care about Ashley, I ended caring deeply about Jessica and I now really want to be implicated with her, there's also characters I strongly dislike (Eric or Jack for example)...But whatever the feeling is, I feel something and that's cool.
Here, it's all about NTR this, NTR that, except it's a bit like Seed of Chaos: it's not well done.
I personally hate that kind of content, normally, but in those two games I'm just like "Hey, whatever. Let's skip the scene and move on." In Seed of Chaos because there's absolutely NO connection or sentimental feeling toward the pseudo-wife (and because the demon girl is more appealing), in GFA because the situations are dumb, the characters are dumb and their reactions are fuckin DUMB x'D
I suppose that post will look like a rant but it's not! Don't get me wrong. I'm not considering it as trash and I'm curious to see what will come next.
For me, my girlfriend's amnesia is a bit like Sharknado: you know it's dumb as hell, but you watch it, laugh when something stupid happens and once you're done, you think about something else.
