My mom did. She understood the M means for older kids. Still she did buy my brother GTA, because he was playing it so much with his older bod-bro anyway. Still, she didn't buy us all mature games. Mostly because I didn't like mature games. Except for GTA, because I liked driving. I liked Mario more. Around 12-13 she just bought me any game I wanted. (Not that she would buy me a lot of games, like 5 a year). She saw that games didn't affect me in weird ways that you hear about those kids who shoot up their schools.
