My 12 year old sister has been playing games like GTA and Saints Row since she was like 7 or 8. I want to get her into fps games like Crossfire and stuff. Started MW3 and showed her the controls. She fucking kicked my PC and broke my CD Rom drive and cracked the corner of my mobo I just bought. I was like wtf? Forgot she's mildly retarded and gets excited easily and throws her feet and hands up.
