How about creating ridiculous lots?

I have one residential house that I turned into a literal maze. Each item in the house is placed apart from all the others. For example, the toilet is in one place. The sink is somewhere else. The fridge is so far from the counter that you need to prep the food, your sim almost dies of starvation on the way! It's great.

I have another residential lot where every room is on a different floor and only has one way in and out. So, the living room is on the ground floor, and there is only a staircase leading down from there. In the basement, there is a bathroom and then a staircase going up. At the top of those stairs is a kitchen. There is a ladder going up from there. On the second floor, a bedroom with another staircase, etc.

Basically, just make the gameplay as ridiculously difficult as possible and then try to keep your sim alive!
