Probably gonna get roasted for playing a porn game but but but I genuinely think this has some of the best conversation mechanics in games. Every conversation is a tight-rope walk where you have to juggle various interests (including potentially porn-y ones!) to get the result you want and this is maybe the only game I've ever played that has properly validated rude and catty dialogue options, never mind made them fun. Moment-to-moment this is Love's best, funniest, most well-observed writing (though admittedly I should probably replay Analogue, and I never played Hate Plus).

And in the interest of not making it seem like i'm reading playboy for the articles, the sex parts are also pretty good, i dunno what to tell ya.
