ESports' debut as a medal event at the Asian Games starting this week will change attitudes and be a major step towards Olympic recognition at last, gamers and experts say.

Gaming was a demonstration sport at the 2018 Asian Games but gold medals will be up for grabs this time in Hangzhou in seven different games.

Players will battle in EA Sports FC, PUBG Mobile, Arena of Valor, Dota 2, League of Legends, Dream Three Kingdoms 2, and Street Fighter V.

For Mayank Prajapati, India's medal hope in the Street Fighter beat 'em up game, the Asian Games opening on Saturday will mark how far he and eSports have come.

He recalled how his father would beat him for sneaking off to play video games.

"I played my first game in the late 1990s at an arcade machine at a market with the two rupees I had," the 33-year-old said.

"It was my first exposure with Street Fighter and I fell in love with the game.

"I got addicted and often lied to my parents, saying 'I am going for tuition', but spent hours playing."

Prajapati, a 3D designer, recalled how his father once tracked him down out playing video games at night, surrounded by half a dozen cheering children.

"I got a lot of scolding… I think I got beaten up," laughed Prajapati, himself now a father to a two-year-old boy.

Prajapati's tale is a familiar one among gamers from different countries.

Kim Gwan-woo, who will represent South Korea in Street Fighter V, told AFP in Seoul: "My parents absolutely hated me playing video games."

They remain "dubious" about him going to the Asian Games, he said, but added: "I think they will be very happy if I actually win a medal."

South Korea, together with hosts China, is expected to be the dominant force in eSports at the Games.
