It's been decades since my last rage quit. Now I simply don't play if it's not enjoyable. No rage, just go play something else and usually never go back.
Actually that's incorrect, my last rage quit was in GT7 online, too many hostile players sapping the fun out of online racing. It was a long time since I felt that anger, didn't like it, haven't touched online play since. (That after nearly 15,000 online races in GT Sport. PD not caring about fair play in GT7 killed my appetite for online racing)
There's so much to play out there, my backlog is huge, why play something that frustrates? I still play GT7, but now in VR, against AI with my own custom races. No lag, no frustration. The AI isn't great but doesn't deliberately target you nor dive bomb in every corner.
But I've been young too. I have smashed keyboards with the keys coming off, taken a hammer to mice that would cause me to die (old roller ball mice), smashed discs so I could never play the game again. Now I go for a run when I feel frustrated, 15K in 75 minutes and all troubles have faded away.
