From what I recall of the game, it has 2 options/modes for Pregnancy content. Endless or Realistic. In Endless.. once you get a girl pregnant she will have that belly forever or until you tell her to birth. In realistic, she will have the baby once some days pass (I think its 30 days?) and if you dont marry her until then, you will lose a lot of relationship points with her. All girls also have a "I got pregnant" talk with you.. and you can be respond being happy (or not) and all that.. its cute. And all sex CGs reflect the pregnancy state.I assume you can bang several girls but only ends with one of them on each path? Also hows the pregnancy here? Do you actually impregnate girls and bang them while they are pregnant or is it just like most games that says girl is pregnant and that's it? Art seems nice.
Some girls start on the pill as well, or will refuse raw sex initially. If you build their relationships high enough, you can overcome this.
I think you can reach an ending with some harems (like the Home Harem, that can have like 3 up to 6 girls iirc). You will probably need to read the wiki/walkthrough to build those harems and reach up to that point
This game has tons of girls and quests.. it WILL consume a lot of your time (if you are like me that are going for all girls) and you can kinda lock yourself out of some content due to triggers/cheating/not doing X quest before Y quest
So yea.. nice game, but do read walkthroughs for your favorite girls.
