I always chose "easy" traits for my sims personality. Often Independent, good friend, happy etc. Hahaha.

I hope that you plays with this family, maybe make a new adventure with your alien baby when it have grown up?

It took a while before I started to really enjoy The Sims 4. I have plans to download some mods because there are things in this game that doesn't work at all (EA Games isn't the best at fixing their problems).
