I told my parents that I wanted Overwatch, and they requested to see the trailer. Not 5 seconds passed after my mother said no (my dad was pretty chill about it). She said it was "too violent." To me, this seemed very immature and closed-minded of her. I intend to discuss this in-depth and not let the topic drop (as she typically does).
Some background info: I am a 15 year old male in 10th grade, I never get below a B in all of my classes. I am quite responsible, very patient, and I can be very persistent. My mother knows I'm a good kid; she knows I would never knowingly do something wrong. The most violent video game I have is Super Smash Bros for the Wii U, and my mother doesn't even like that. She is very overprotective..

So I tried to have a civilized conversation with her. It was mainly a bunch of "I don't like it" and "it's too violent." When I ask her to elaborate on that, she says that she's given me enough detail and that I don't understand (when all she said is "I don't like it."). She has made all of her judgements based off of 5 seconds of gameplay she's seen. I ask her how she thinks it will affect me: "I don't like it, it will mess with your brain." When I say I'm 15 and responsible and things like that: "I wouldn't let your father play that game it's too violent" (he's 54)
I'm honestly thinking of asking them to add funds to my account and telling them it's for a different, more friendly game. I don't want to lie to them, but it seems like my only option
