Okay, this is the second part to my original editorial. I have another theory on why people enjoy playing games so much. I think that is most likely that a person play games for many reasons not just the first one I had suggested. I think that one of the most important reasons why people play games is because of the challenge.

They like beating opponents equal to them to show how skillful they are. They like the fact that their opponents will think of new ways of beating them and then counteracting their strategies with their own. People can be seen doing just about anything for a challenge. This is the whole theory behind the Guiness book of records. Here is an example.
