To me it's not a game, it's just a more elaborate, embellished porn simulator. I started my Koikatsu adventure with Sunshine, and switching to regular Koikatsu out of sheer curiosity, I can say that the only thing you can see is actually the graphics, which are better. It's hard to call it a game at all, where the challenge is zero, ( in Koikatsu there was at least a system of progression drop when you answered wrong, admittedly those answers were so few that you can learn them after an hour of playing, but still). The Topics mechanics are actually cool and fresh, but also not extensive. Something Illusion should do ASAP is to make Mod tools available to create new dialogues/topics/meetings etc. With such an expansive community, they wouldn't have to do anything, because the community itself would create regular DLC worth of content - which it does now, but focusing mainly on visual aspects, improving physics or "improving" porn for known reasons. For me, as someone who's had Koikatsu for 2 weeks, it's not even much of a dating simulator, because it's hard for a character who has less lines of text than a 3 minute song to make me want to talk to her for anything more than hitting max is progress bar in the top left corner of the screen.
