4. Animal Crossing (series)
Ah, much better you would think. A peaceful life simulator, with friendly animals. What could go wrong here? The problem with Animal Crossing is that it isn't limited to just children playing it, adults play it too. For example, in my Animal Crossing town, thanks to one of my friends, there's a penis constellation in the sky, and my residents greet me with very lewd sayings. Of course Nintendo steps in and tries to censor the worst, but people find ways around it. There's also Nintendo's strict friend code system, but that doesn't stop Blanca the cat coming over with a butt drawn on her face if your kid has been on WiFi.
