You're on Xbox Live. You're at an arcade. You're playing at a friend's party. You get matched up with someone that doesn't know the first thing about the game. They pick Ken. They walk right up to you and shoryu you in the mouth. You shake your head and mutter, picking blond white boy out of your teeth. Match continues. You bait the shoryu and punish. He starts throwing out crouching roundhouse and jump back hadoken. You're walking into his “offense”. He gets confident. You make love to a wake-up Ultra. His. You lose. You eat an entire can of salt and vinegar Pringles.
Sound vaguely familiar?
Think about the reasons why you'd get upset losing to that Ken. There's a disease in your game. Those reasons are silent symptoms.
