One of the things that i really like about every jsk game is that they actually give you a fucking choice, most of the other hentai games just force you to rape, sexually harrass someone or get harrass againts you will without any choices, even if those other games give you the choices to deny those things, the outcome end up being bland and lame as fuck most of the timeThe romance I feel is very empty. There's a shit ton of romance games already, and he's really not great at such routes. They're not that interesting. The only good thing about those routes are the poses. But the rape, mind break, etc etc... Now those are the best of the best of the best, sir... with honors.
Here though, jsk actually give you a choice to whether do evil or good things and each path is both rewarding and fun especially with the post-game extra modes
So if a jsk game lost it choices to whether do bad or good things and only focus solely on rape and mind break then it pretty much lost most of the things that made the jsk games so unique and fun
P.S: i think the reason the romance is empty to you because you only focus on and into the rape stuff wayyyyy more, i dont have any problem with the romances on my part
