This game was once the absolute pinnacle of college-themed western VNs on this site, but as time went on it got dragged down by two main factors for me: bad sex scenes and being forced to view the stories of certain characters.
COWGIRL -> COWGIRL (ANAL) -> MISSIONARY -> CUM
Starting with the sex scenes, it's ironic because DPC is clearly a fucking PRO at posing/dressing girls to look sexy, despite the occasional VERY dubious ass and tit proportions (I actually stopped playing the first time I saw Bella, and only got through the game on a 2nd try).
However, most sex scenes (Especially recently) simply boil down to a bunch of poses with the MC pumping until he cums. Sometimes the girls are shown to cum, sometimes they're not, a few times there's even 0 dialogue and it's just mindless clicking - I get that the author wants to focus on the non-sex writing, but this is a porn VN, so that's literally half the expected content? Sorry to break it to you DPC, but there's more to sex scenes than simply what the guy does and feels, just like there's more to an action scene than just a single shot of an explosion being repeated over and over again.
If this game had the same attention to sex scenes as some others, it would truly shine despite its age. But if I just wanted an animated slideshow, I'd look at porn gifs online. I can't imagine someone putting that much effort into modelling, rigging, animating, and then shrugging their shoulders at actually writing the scene and saying 'Fuck it, just flip through poses until it's done'.
'LOCAL STUDENT BECOMES GROUP THERAPIST'
The second big issue is that the game forces you into a gang of friends (Not the fraternity, most of them are great) despite how you might feel about it. I've played other games in which you can choose to grow a friends group, invite people, or just wind up alone, but BADIK is adamant about you liking ALL the main girls and hanging out with them. I would have gladly left this group and skipped all those scenes, even if it means less content, because I can't stand most of them and like to have, you know, CHOICES in a visual novel.
I laughed when the game asked me to budget for giving them Christmas gifts, since I had no emotional connection to any of them but one and couldn't care less. It quickly becomes clear that the author controls the actions of the MC far more than you do, and even when fully on the DIK path he behaves more like a therapist than a college student. None of the 'main' girls can be sided against, shrugged off, or even ignored - you HAVE to befriend and hang out with them all, even if you're not romancing any of them. You'd think going on the 'Others' path would mean you're not actually interested in the main girls, right DPC?
So yeah, two issues that built up over time until they snowballed in Episode 11, where I started skipping unread dialogue for the first time - the telltale first sign that a VN is dead to you.
If you're fine with kinetic novels and consider the 'adult' part of adult visual novels to be the MC brainlessly pumping away while paying 0 attention to the eroticism of what the female partner is feeling, then this game might just be 4 stars for you. But the fact that it's also updated ONCE PER YEAR, features models older than God and shows no end in sight, definitely keeps it from ever reaching 5 stars imo.
(One more thing - the music choice really needs work. Never thought I'd watch a girl get railed in the ass while the OST sings a family carol about Jesus being born, but... yeah.)
