When I was younger my competitiveness often led to me getting pretty angry if things didn't go my way. You could say I had some issues and was pretty stubborn. It's still there sometimes but most of the time I can control it. At the very least I never show that side to anyone.
Anyways, I'm thinking CS:GO would be the game I'd raged at the most just because that's all I used to play when I was younger. I mean I got mad at practically everything, but it's just that I sunk so many hours into that game at the time that it's technically what I raged at the most. I hate looking back at my younger self.
