I'm not sure why we've reached a point where a porn game requires real-life-job hours, but here we are.
Actually, before we get to that, this game is unintelligible in English. I've played more than a few Russian QSP games, and you get used to seeing the small disclaimer "Still contains some machine translation." Well, this game is entirely machine translation, and it's the shits. I threw in the towel when I was introduced to a character named 'Roofing'. That's not his job; that's his name. Goodbye immersion.
A game like this lives and dies on immersion: you're taking on the role of a character in a world. You have to be interested in that world and the people in it. Chatting to characters who spit out gibberish, or worse, trying to seduce one, can't build up any kind of anticipation. They might as well be empty text boxes for all the emotion I've gotten out of them. That alone would make this unplayable, but...
The grind: it's fucking bad. You do the normal QSP-game style reputation grind with every character you meet, and it takes forever. The same interactions, day after day after day, with no forward momentum to even indicate you're getting anywhere. I played with the cheat mod, and on occasion I had to check it to be sure I was doing anything at all.
Multiply that grind by all the characters you meet and you might as well put your genitals away: you aren't fapping anytime soon. I hope the occasional still image of a topless pornstar is enough to sustain your lust while you grind like you're playing an F2P mobile game.
Oh, and I should mention: all that grind I'm talking about is after cheating heavily. My character's stats, their own long-ass grind, I maxed with the mod. I was as intelligent, beautiful, rich, well-rested, and full to the gills with food. If you don't use a cheat mod it is not a stretch to say you'll spend your entire time in this game micromanaging instead of masturbating. What is the point?!
I think this developer may have forgotten that the point of a game is to have fun, and the point of a porn game is to have fun and then cum. You won't be doing either of those things with Big Kuyash.
