Video games as a "hook?"

I know how absurd this probably sounds, but here me out. In the world of E-sports, there is an annual competion called the Wolrd Cyber Games (WCG) In this tournament, over 50 countries send 1 to 2 people per game to represent their country. Last year i qualified after 2 national tournaments and represented Canada in Seul Korea. Would this be a good hook for an admissions essay? or do colleges want something more practical… I was second in Canada after all!
