Gaming 4 Money

So this is in regards to a thread I saw asking about ways to make money online...
Through experience, gaming is the most fun and less painful way to do so?
Why? You may ask, is because I am sure most of you here like gaming, and in MOST games, there is some type of currency or service you can provide.
As long as the game you choose has a type of tradeable currency or service you can offer, you can easily sell it.
An example would be MapleStory, whether it's private servers or the real deal, you can sell services or currency and actually make a living off of it.
No, I am not just "saying" that, I know so through some people that I know that are selling services, it may take a while to start up reputation but after you are reputable enough, you will start seeing your efforts pay off.
