Well. Basically, it's a life simulator. You create people, you build them a house, give them everything a normal person would need such as a bed, TV, Job, etc. Then the most difficult part is tending to their needs. If you leave them to do whatever and you don't let them go to the bathroom, their bladder meter will fill and eventually they'll wet the floor.
If you don't let them sleep, they'll just collapse on the floor and sleep until their energy levels go back up. And sometimes there's a bunch of hilarious disasters. Sometimes they'll accidentally leave the stove on and start a fire, and sometimes they get electrocuted from changing a lightbulb. There's even rare occasions where they'll get abducted by aliens.
The list of hilarious things about this game can go on and on. There's even one cheat a friend showed me where somebody can die from a satellite returning to earth and landing ontop of them.
