Thank you Erth for your answer, complete and educated, really thank you.
In twitch there are not only young viewers, for example I am over 40 years old and there (in twitch) I am meeting people of my age range and similar tastes, it is not just about games, but also musical and artistic tastes. It does not have to be an exciting and fast game to be able to enjoy its broadcast, some spectators like calm things. My intention in opening this thread is to encourage people to make known this toribash, a kind of mixture of martial art and chess in 3D, where sagacity and mental speed is the important thing.
