Gaming, it's a term that means many things to many people. Gaming like anything else exists on a spectrum. On one hand, there is gaming at its least concentration. This is what is known as casual gaming. On the other hand, there is gaming at its most and most serious concentration. This is what we call tournament or pro gaming. But, is the spectrum even that easily defined? Is there much of a difference between the two? What is it that makes a gamer "Pro."
