I wasn't allowed to watch The Simpson or any of the Seth Mcfarlane adult cartoons like Family Guy. I also wasn't allowed to watch the Saw films.
Other than that though, they weren't super strict. I remember watching one of the American Pie films with my dad when I was quite young, and several gory horror movies with my parents. Me and my sister played Quake II a lot, though if feel like if shooter games back then were as detailed as they are now that may not have been able to fly.
Sex scenes in movies? My parents didn't care. Blood and gore and scary scenes? Totally fine. Violent video games? I mean I only had Quake II to judge, but probably would have been fine. But a fun cartoon about a family with some adult humour someone of my age wouldn't have even gotten? Absolutely not ok!
