Re: Best games with pregnancy
There are games with pregnancy as a game mechanic, pregnancy as a story aspect, and games that have both. Personally, I enjoy the ones that have both significantly more.
Of those, the most (in)famous is Violated Heroine, although production on that project has largely... I won't say stalled, but it's very, very slow and doesn't have a whole lot of focus. It's also quite dated graphically. Still, there are a couple hours of solid gameplay there, and a fair bit more if you're willing to go through unfinished or less polished material.
Corruption of Champions is a text game that has QUITE a lot of both parts. It has a few issues with "muh waifus" on the part of the developers, but overall it's a very solid text adventure game. Some folks have put together an image pack, too, if that's more your style.
Trials in Tainted Space is the (as yet incomplete, but progress is both constant and brisk) spiritual successor to Corruption of Champions, and has a much higher production value. Still a text game, but a well done one, and worth a play if you haven't tried it yet.
Also in the text game category is Fall of Eden (a sort of cousin project to CoC in a lot of ways), which I haven't personally tried but have heard decent things about.
There's an upcoming game by an established creator featuring it (similar to VH from what I could tell from the pictures, as I'm not fluent in Japanese) but the name escapes me at the moment. I'll try to dig up the forum link when I have a bit more time.
