I have been circling around the web for years trying to find the best interactive pregnancy/impregnation game there is. I have found many that are great, but there is always a problem. Either it's not finished yet or the content of pregnancy is not enough. Mostly I'm looking for games that you play as the girl, and you have the means of protection, and you can choose if you want to use birth control or not, also what type. Incest is an added bonus, and if incest is included then hypnosis or mind control is just as welcome. I know that we have the pregnancy tag which I'm following of course, but sometimes games that actually have decent preg and impreg content don't have this tag.
Good games that I have found so far:
Girl Life ETO
You can buy condoms, pills, fuck your siblings. Pregnancy and fertility is being monitored and tracked on so many levels I got lost in the code they use. One of my favorites.
Son of a bitch
Now that pregnancy and birth is being expanded to more and more characters it's worth mentioning. Your mother takes bc pills and I hope it gets an update soon.
Newlife
I'm amazed by the amount of sex interactions in this one. Also choice to take bc or use condoms, but also there are traits that give you a bonus on fertility and make you aroused on the thought of pregnancy.
Niicrii's Flash Games
Now the games have condoms, condom sabotage and stuff. In MILF Saeko I really liked the Mood changes. She was either asking to be impregnated, or being anxious and neutral about it, or absolutely despising you for it.
Violated Heroine
Contraceptives. You have a fertility tracker, have safe and unsafe days. Can get pregnant any time literally.
Lab Rats 2
This game has been constantly evolving into something that I've been waiting for a while now. All the characters are impregnable without an exception. It has a "Realistic Pregnancy" mode and "Classic Pregnancy" mode. The difference between the two is that some people may take bc and may not (while birth control is not 100% protection, if you don't want her to get pregnant use a condom I say) in realistic, and classic mode is, the regular "If she takes bc you disable pregnancy for her". Also fertility rates are all over the place depending on age, serum boosts, and also what day it is. So there are safe days, normal days, risky days and high risk days, but it gradually changes with every day.
The conversation between you and the woman changes a lot depending on what opinions that woman has. She can either love or hate creampies, or bareback sex, or just vaginal sex for that matter. So I advise everyone to play around with them. Love creampies but hate bareback sex can have some interesting results.
Highly recommend this game, as it has a lot of content, and I suppose twice as much on the way.
There is also a mod for it which I personally always install. It extends the amount of content even further with more story events, better company management, lot of more research options and also you can give different fetishes to npcs(There is also a breeding fetish which might be interesting for you.), and a lot lot more.
College Daze
The story is pretty interesting, from magical powers to demons and succubuses. I was thinking of putting this one in Honorable Mentions, but the amount impregnation you can do is too astounding to do that. I remember that I rolled back and reloaded a lot of times to see all the content it has. There are lots of characters who are always impregnable after a while, and you can take different routes as well. For example: Pay for them to let you impregnate them, make them too horny to care, alter their mindset into accepting it, or change their personality, maybe even make them your slaves so they can't say no. Lots of options really. I had a blast with. Content comes in little bits and pieces, but the thread is usually updated when there is decent amount of content to explore.
Simple Days
Moved this game from Honorable Mentions to the main section. Part 2 now has a fully implemented cycle system and the girls react differently if they are fertile or not. This game focuses a lot on impregnation and pregnancy risk. The english is slightly broken, but you can easily get past that.
HONORABLE MENTIONS:
Artificial Academy 2
Girls have dangerous, safe, and normal days. They have different reactions when you cum inside, different traits, and different virtues which is a nice bonus. Pregnancy is "stat based". Cum inside too many times on a dangerous day in one week and its a pregnancy ending.
The Company
Still in alpha state, but has a chanced based pregnancy system, and incest combined with mind control. Decent title, also you can give your mother a real dick and if you are a female she can get you pregnant. Not something I see very often.
After these I can only remember Choice Pregnancies, with "if you cum inside she gets pregnant if you don't she doesn't" type of things. If anything else comes to mind I will post it, otherwise I'm up for suggestions.
The Twist
The updates are really slow with this one, but it has finally reached the point where you can get a character pregnant. I'm not sure its only one character, but one I know for sure. However it's nothing interesting yet. You just switch her pills, and have sex with her. Maybe in the future there will be more?
Summertime Saga
This game has come a long way since it's release. The pregnancy is basically a lucky wheel minigame, but still worth to mention.
