There's no question that e-sports have been gaining popularity and are even beginning
to shirk their statuses as niche interests, but the Olympic Council of Asia has given the gaming industry a credibility boost after announcing that it will award medals for e-sports at the 2022 Asian Games in Hangzhou, China. Though the Olympic Council of Asia didn't specify all the games that would be included as medal sports, it mentioned FIFA 2017 as well as "MOBA (Multiplayer Online Battle Arena) and RTA (Real Time Attack)" game such as League of Legends and Starcraft II.
To be sure, current gaming tournaments offer far more money and even fame when compared to the Asian Games, but the inclusion of e-sports in that traditional sporting event could represent a step forward in e-sports acceptance among the general public.
