SEATTLE — This summer, after spending a little too much time in communion with his Xbox, my 8-year-old son told me he’d like to be a professional video game player when he grows up. My 12-year-old daughter watches YouTube videos of people who record themselves playing video games, devouring them one after another like a box of chocolates.

So in August, when the opportunity arose, I did something that may earn me the title of Best Dad Ever or World’s Worst Parent, depending on whether you’ve reached puberty.

I took my kids to video game little league.

If you haven’t noticed, video games are now sports (“e-sports” is the favored term). No, they’re not sports in the cardiovascular, tendon-tearing sense. Still, competitive game-playing requires dedication, cheetah-like reflexes, teamwork, tactical smarts and phenomenal concentration.

Elite e-sport stars make millions of dollars a year at tournaments and are watched by tens of thousands in the stands (and millions more online). In early August at KeyArena in Seattle, five young men who call themselves Evil Geniuses defeated a Chinese team on the multiplayer battle game Dota 2 and won $6.6 million.
