How is this not a bad thing? I certainly wouldn't want my son or daughter give up as soon as things don't work out. That kind of behavior spills into the rest of life, not just sports.
The changes in schools and helicopter parenting are these causes.
League of Legends, Overwatch, Counter Strike etc etc.
At the time of my comment, Twitch is live broadcasting the Hearthstone World Championship, Duelyst Pro League, Vainglory Evil Eight, Starcraft II World Championship Series Global Finals, and SMITE Pro League.
eSports tournaments have paid out over $100 million in prizes. Some of these tournaments are being carried live on cable channels in other parts of the world where they're more popular.
FIFA is somewhat popular.
