The whole issue here is, it's just a video game, but many of us are really competitive and it's probably part of the reason we all play. So, if you're going to get pissed, like many of us do, there are better ways to deal with it.

That's one way to deal with it. Expensive, yes. But it doesn't include bitching at my opponent who just beat me...
