Good article... I don't play online gaming and I suck at copetitive... but thanks for the "Take a Break" part... I needed to read that :) haha!!

The only advice I want to give is to format it better by using the title tags ### and bold tags ** so If I were you I'll write this part:

So, first rule you have to remember is that it is just a game. You play games to be entertained. But of course, when you are losing, it wouldn't be fun at all and will become very frustrating.

Like this:

### First Rule: Remember is that it is just a game.
You play games to be entertained.
But of course, when you are losing,
**it wouldn't be fun at all and will
become very frustrating.**

...

so it would be like:

First Rule: Remember is that it is just a game.

You play games to be entertained. But of course, when you are losing, it wouldn't be fun at all and will become very frustrating.

and format all of the article this way...

Believe me it will look much better... it will be more awesome if you could get pictures. but it's hard to find public domain ones for gaming.
