As a heads up, this is more or less, me venting...
I play a tabletop game known as Warhammer 40k. I have an army that is a wee bit strange but works really well. My brothers have gotten into the game as well and have chosen armies based upon what they liked. My army, because of it's composition and their composition, is actually remarkably effective against both of my brothers (I went pure 100% shooting, if I get into melee, Im dead faster than... anything... but I can usually stay away). Unfortunately, one of my brother's has an army that is a hard counter to the other. In otherwords, one of my brothers gets stomped pretty badly when he challenges either of us. That isnt to say he doesnt do well against other people, he does, but not against either of us. Bad match ups are bad match ups (for anyone who plays Super Smash brother's Brawl, try Lucas vs Marth. Its bad lol).
If he had good sportsmanship, it would be fine, but he freaks out when things go wrong.... over and over and over. It's annoying as hell. It makes it not fun to play. I hate it when people start yelling at their bad luck. I have games where I get curb stomped to the ground and then some. It sucks but you deal with it and keep going... and play the game out anyway. Who knows, maybe you will still win.
I just hate it when people ruin it for everyone because they can't control their temper or emotions.
Anyone else have an experience they need to vent about?
