tl;dr -- Dude I was best friends with from 16-20 would get super pissed off over Dance Dance Revolution, make a complete fool of himself, was a huge fucking brat, and all of his friends followed me in abandoning him a few years after I did.

I used to be really into Dance Dance Revolution in my later teen years (traveled to enter tournaments and stuff), along with the majority of my closest friends. My best friend from when we were 16-20 used to get so pissed off over the game that he would become a different person. He would curse loudly in children-friendly areas, slam his fists on the arcade machine, kick the machine, kick whatever was in sight, all because he had a few less-than-perfect steps on a song he was trying to get a perfect score on.

It came down to two incidents within one weekend that lead me to decide to cut off all contact with him. We had DDR friends visiting from Virginia (we live in Pennsylvania), so we were touring a lot of the different dance machines in the area, and we planned on hitting up Carnegie Melon University in Pittsburgh, as they have a rec room with a dance machine.

We took two cars, just enough space for all of us. When we got there however, for some unknown reason, the machine's volume had been turned off, making the game pretty much unplayable. Kyle was SUPER PISSED, went silent for a while, wouldn't respond to anyone, and took a turn on the machine. Shortly into his set he started getting angrier and stomping excessively on the dance pad (you only need to lightly tap it usually, he was stomping the shit out of it).

Anyways, he walks off mid-set, and just leaves. Without saying a word, with girlfriend tailing him, he just left us all there. Sucks for him, he went home to have a shitty time and we wandered around Pittsburgh having a blast. Turned out one of our Virginia friends had a buddy going to school in Pittsburgh, and was nice enough to provide a second car to get us all home (he drove 25 miles out of his way and spent the night with us, awesome, awesome dude).

The second incident happened the same weekend, this time at a different arcade. I don't want to drag this out forever, but in a nutshell, Kyle had a slight miss-step during the end of a song he had been trying to perfect for a while. He pulled his arm back as far as he could and shattered the fucking screen of the dance machine (not the monitor, the plexiglass over it). It shattered like real glass, created a gigantic mess, and he fled crying with his girlfriend once again right behind him and a bloodied hand. He was 20 or 21 at the time.

I've hardly spoken to him since, and it's been about four years. Since then, almost all of our mutual friends growing up have abandoned him, they just can't stand his negativity and insults any more (even the girlfriend, who was never in our circle before him, but left him and stayed in the circle). We all still know how to play DDR, it's like riding a bike, but none of us take it seriously anymore (I might play a set or two every 3-4 months). Kyle however, I hear just bought two dance machines of his own that he now keeps in his apartment. When a video game gets in the way of your relationships with people, you need to grow up.
