That event was shocking to me considering i played madden growing up but not so much as I have been playing different games and been focusing on Street Fighter V AE.
I heard it was over not only a loss but also $50 that the man lost too as well so i don't understand why someone would resort to such an unnecessary extreme. So what if you lost and the money too? You pay to get in and play anyway so suck it up and take the loss to learn from it instead of taking other people's lives because you can't handle losing and only care about winning.
