So, over half-way into the game, I really didn't understand why everyone was upset about the lack of choices. I mean, yeah, there were fewer choices than in other similar games (Sisterly Perverter being the gold standard in that respect, imo), but I thought it was fine overall. And then I reached the end of the game.
I think the real problem is that the choices you do have aren't that meaningful (spoilers from here own out, so be warned). No matter what the MC does, the harebrained idea of posting porn videos will happen, Emma will find out about the MC and his mother, and, in the end, the MC will get screwed over. And I think it's particularly frustrating because the quality of the writing fluctuates. To be honest, I got a bit of a GoT flashback toward the end, as seemingly situations were contrived to bring about the concluding conflict. So, a mother and her son go on an overnight trip, and the first her husband thinks when he finds out she's not been truthful about where she went is "Oh shit, she's cheating on me!" How does that make sense? Even more silly is the fact that the bigger fight between them happens over condoms. Seriously? The best she can come up with is "Oh yeah, I've been having male prostitutes coming in here"? He is there during the night, so presumably she'd have all these people coming around in broad daylight, with both children around the house? Would it really be that hard for her to go "They're ours, dumbass" and then storm out? You could easily have and ending where Mia and the MC end on good terms. Mia and Emma are over (that situation can easily be achieved in a million other ways, given all she's done in the course of the game), so obviously her only source of income has run dry, the only choice is for her to take up her aunt's offer, "but you can still visit" and well... it's a bit of a "if you love her let her go" type of situation. We pick up in the next game after two years and they've obviously drifted apart.
There, now we have a positive and a negative ending. And it feels like the player's choices impact the story...
