Right now, I'd say Conception 2. If there's something in certain anime that puts some people off, then Conception 2 definitely has it. One of the main game mechanics revolves around pairing up with women (sorry, high school girls) and making children with them that you use to fight monsters. It's a process called "Classmating" explained away with tons of JRPG jargon and while it technically isn't intercourse, the game never misses an opportunity to heavily imply that it is for the sake of laughs and fanservice.
When you enter dungeons, you and one of the girls who comes along have to get into your "battle suits" through a sexy transformation sequence which puts any sailor moon transformation to shame when it comes to panning in on the girl's body parts and putting her in an outfit that shouts "Ogle me guys!" Really, I'm not grasping at straws here. Some people argue that it's supposed to parody the harem and magical girl genre, and I could believe it's a possibility, because there simply isn't any subtlety in this game when it comes to embracing the aspects of harem and magical girl that make non-fans uncomfortable.
Basically a friend recommended it to me, and I'm currently deciding whether or not to stick with it. All the girls are kind of one-note personality-wise, but this was made by Atlus, so there's still the possibility of future character development if I stick with it. Of course, because it was made by Atlus, I cannot stop comparing it to Persona 4, which is definitely a losing battle for this game. Hopefully, there's some hidden genius behind the game's plot or mechanics that I'll find if I press on.
