I get upset, but it's only for like one minute and I'm basically done after that. I'm also not a controller-throwing manbaby who's out to destroy his things after an L.
That said, it's all circumstantial for me, though. Take Warzone for example. My labeling of that is game is "love the game, hate the players". I do tend to get pretty tilted when I'm decently deep into a match and I get killed by three people huddled up in a corner of an attic with Ghost as a perk. I get killed all the time in that game by better shots, but it's maddening when a group of people has chosen a completely random hole to dig themselves into in a remote location on the map. To this ... I curse and rant with my teammates for one minute and then we're over it.
