RimWorld, it's a wonderful game that seams light on the surface, but when you start to play it, you realise how much you have to manage, from food to happiness and even the temperature and clothing. Although there may be things that make it not family friendly, the gameplay makes up for it.

If you start to get bored, try out the 3 DLCs that are for it, and that should spice up your gameplay, and if that still does not help, go and check out the huge community for modding and they will have that fix for any issue you may have.
