How do you try new things in your gameplay?

I like to have families with either generally happy lives or otherwise, to change that I've done random things with different stories either keeping with that idea or not. In order of the photos, just four.
1. A male alien under a scientist's protection fell for her and ended up pregnant when she wasn't sure about the idea he meant to ran away he was found and brought in to another holding facility a windowed room away from their child where she was allowed to visit.
2. The maid was in a sort of rags to riches sort of story but since she met Mila Munch and ended up the maid she was meant to prove she could make a living without her father's inheritance. Her evil stepmother only agreed to keep it going after he died as there was a iron clad contract protected by and old friend of her father's.
3. They were meant to have a family and only make a living off of collectibles found and things that mama dearest stole they raised six children in that little shack adding on bit by bit until they were all closed in. That legacy was a trail of bad decisions fun though.
4. The couple returning from a wedding, I cheated the blond to be related to Bjorn so the girls are his nieces he stepped in when Bjorn wouldn't be a part of their lives.
fun times.
