There is a correlation. Both involve guns. My brain connects the two. It doesn't mean I think that CoD caused this. I just can't pull the trigger on a game tonight, after watching the events of the day on the news. It's not like I won't play Black Ops again, I'll probably play tomorrow, I just don't feel like playing it tonight.
This highlights an issue with people as a whole.
People die to gun violence constantly in the world, there is genocide taking place in parts of the world as we speak. Then suddenly something happens in your back yard and you give a s***. Sad really.
I always tend to think a lot about things like what happened at the elementary school. I think so much about it that I tend to avoid playing video games. It's not because I believe there's a connection between the massacre and video games; it's because I can't keep my mind off of the damn thing. It doesn't necessarily help that people are saying that video games are the cause of it; that only makes me think deeper. I guess you could say that I am methodical in nature. However, once everything calms down and people start talking less about it (or I start seeing less of it), I will go back to my usual routine.
What determines whether a game is good is your experience every time you play the game, not the opinions of other people (unless you let it do so).
