erm, broke my Pentium 2 Laptop back in the days when they where still new on the market. lol

LOL, I actually got a Boxer's fracture when I punch the wall. Turns out, the behind the chip-rock wall, there's a concrete wall.

my father got a tendonitis at the shoulder playing AoE II :/

i once broke a controller by mashing very hard in bejing olympics 2008...

I was Placing my original Xbox into my pc case and sliced my thumb down to the bone when i case removing the in aluminum shell.

When I was a teenager with poor control of my emotions I broken a couple keyboards. That's about it :P Spilled a few beers in frustration since then, but never broke anything.

I've never really...Broken anything, really. I've gotten frustrated when something was just too damn hard or demanding, but I had to do it anyway to get full completion. I think the worst injury I've ever gotten was a blistered thumb way back on the old NES D-Pad.

Well let's see if I can recount. I know I've lead to things breaking in my frustration before...

I used to throw my controllers occasionally when I got pissed off. Then again when I finally did what I needed to do. You know. All like "YEAH! YEAH! IN YOUR FACE!" and stuff. Who's the man, game?! ME!

Everyone's prone to smacking or punching their knee/leg. At least, everyone I've known.

I once broke my headset because I sneezed really hard clinching a CAL Match for CS 1.6 a long time ago. Needless to say, there was laughter to be had everywhere and I died. From then on I was known as the least stealthy person alive, even though I love playing games like Deus Ex and Metal Gear Solid all stealthy at all times.

Never had a keyboard break or anything though. Not because I threw it. Although this one time, I guess it counts, I clicked my mouse just a bit too hard in a knee-jerk reaction to someone I wasn't expecting coming 'round a corner. My left mouse button tore off and the spring flew at my face; it cut me. It sucked. Game over until I got a new mouse.

Hurt my arm trying to play MadWorld on Wii.

I also have difficulties with some action games during the colder months of the year, my fingers simply can't keep up when the cold causes me some pain in my joints.

I once have broken my finger. It was not because of any rage, but by pure accident and I´m afraid, that it is better to not tell how exactly it happened.

For the last two or three years I control myself as much as I can, I don't even remember when I raged for the last time when playing a game, not to mention hurting myself. I also try to avoid frustrating games and situations as much as I can. Anyway, I remember getting a few bruises on my hand when I hit the wall with a fist. I also damaged the mouse right click and gamepad (right analogue died and some button got stuck), good thing they were both crap/cheap.

Destroyed a couple of keyboard mouse and 1 screen when i was playing LoL

My mouse and keyboard have suffered from BF3 mouse broke completely by smashing it into the table keyboard is still working more or less but some key are missing because they broke

I blame the lag.

I broke an original nintendo ds by smashing it on my lap in a fit of rage because my pokemon save went corrupt and i had almost beat the game. back when the original ninendo came out, the entire top screen came clean off, I don't even know how, I guess I lift

in mgs4 i got knocked out and i had to spin the joystick and i tore a perfect circle out of my skin

My chair fell over with me on it while I was playing Super Meat Boy once. It hurt my pride, my headphones, and my arm.

I once destroyed my Nes controller cuz' of Kick Master (i had a "pirate nes" or something like that with yellow cartages) but it was kinda cheap. 5euro, and the games where like 2. I have my collection till these days.

And just a few weeks ago, i got Kung Fu Strike, started playing it, and after a half hour i think, my right arm was hurt as hell.

I have not.

The most enraging game I ever played was God Of War 3. I also played it for the first time on Hard, just for the trophy. I remember throwing the controller so many times to the wall or throwing it to the ground that it almost broke.
As far as physical injuries are concerned, when I used to play Trackmania for about 10h a day I remember having really bad bruises in the tips of my fingers from the keyboard arrows and also the same result from playing Guitar Hero for hours...

I dislocated a knee playing ping pong. Tore it out so bad that it wouldnt stay back in socket. I did the other other a week later hopping around without my crutches. It left me in a wheel chair for a couple of years in high school until I was old enough for them to bolt my knees back in and reshape my tendons to fit in place. Not a videogame, but your topic didn't clarify. :)

hurt my wrist, couldn't fap! :(

Well, it wasn't because of a game but just a bad PC. My old(and by "old" I mean "ancient") first PC was pretty shitty. It had the annoying habit of not starting until it got restarted at least 10 times and punched or kicked at least 2 times... Surprisingly I never damaged any limbs on it, but it's floppy and normal disk readers were caved in. ^_^

Put Dungeon Keeper 2 in the toaster as a kid, along with another blank cd to burn a copy for my friend.
Filled the bottom of my pc tower with water to water cool, leaked out, hit my 5-way plug connector...

Frankly, I did a lot of stupid things as a kid.

I broke my mouse once
