So, most experienced Sims players should probably be familiar with the 100 baby challenge. For this of you who are not, it is a challenge where a women has to have 100 babies over the course of a few generations. This is like that, but easier.

!!!!!!!!!!!!¡!?!!!!??!!!!!!!!!!!!!!!!!Everyone in town challenge!!!!!!!!!!!!!!!!!!!!!!!!!!
You sit on the train, and watch as Willow Creek (or other neighbourhood) slowly comes into view. Back home, you made a reputation for yourself of being a cassanova, butt Willow Creek is a fresh, new start. When you leave the train station, you immediately forget your resolution, and start flirting with her. Flirting turns into a few drinks, then that turns into kissing and hotub woohoo.
A couple of months later, you get a panicked phone call from her saying that she's pregnant with your kid. You get a rush, and set yourself a target of getting every woman in town pregnant.

Cas:
Create a man. He can look however you want, but he has to have strange coloured eyes. This is because you need to throw some strange genes into the mix.
Make him romantic and non- committal. This will come in handy when romancing women.

Set him up with a house, then put his funds back to 500 simoleans. He is not allowed to have a job, but he can go out and collect.
You can only try for a baby every 2 days, so set lifespan on long. Short if you want a challenge. Then the rules are simple: have a child with every woman in your neighbourhood, then choose an heir to carry it on in the other neighbourhood. The aim of the challenge is to get a child with every woman in the Sims 4 world!
