Imagine you are playing chess, and not just playing chess but you are in a competitive chess league. Now imagine that you are playing a game of chess with 5 people on each side taking turns. Now imagine that your 4th member during his turn likes to trade your queen for a pawn, essentially wasting everyone's time. Now imagine that you try explaining to him why it is bad to trade your queen for a pawn and he tells you "GAH CALM DOWN ITS JUST A GAME"
Another example: Imagine an NFL game. Now imagine that one of the players gets the idea in his head that either it would be funny to, or is just dumb enough to think that you are supposed to kick the ball around the field. He spends the rest of the game running around kicking the pigskin around the field, trying to hit other players with it.
Yet another example: you are trying to play a board game with some friends. One of your friends during his turn just flips the board over, completely ruining the game. You and your other friends meticulously spend 2 minutes setting everything up again to the best of your ability, and then your friend on his turn simply flips the board over again and again and again and AGAIN.
Its not that people flame at this game, infact it has nothing to do with the game itself, it is more about human behavior. If someone behaved the way people do on here in any other game, or activity, I would treat them the same way. Not that i flame much anymore, but i definitely understand why someone would.
