I though this was kind of funny today as I was stumbling across articles on the various things people do when it comes to earning money and many of it revolved around entertainment based games. This included things like video games where people are actually being hired as consultations to say learn the best ways to defeat a level in a game.
It was interesting too to see that almost every popular board game you can think of has some kind of tournament as well where people compete for real money. Kind of makes you think of all those times like when your parents tell you to stop playing so many video games or to read a book instead of playing a board game. Like with those examples you can pretty much make money with any kind of expertise that you gained. Fun way to do it too I must say.
As well, another thing this kind of made me think of is how you can pretty much create a market for it. Example, if it is a hobby then holding competitions and events where people compete with each other can be the start of a sport on its own, so to speak.
