The Manila Major was one of the most successful tournaments run by ESL. The low cost of the tournament along with high exposure and the quality of games made it a perfect tournament to run. ESports companies usually run on a huge loss and having a tournament with such good margins definitely is a boon.
That being said there is also the added aspect of a huge number of the MOBA player base coming from Asia. As such ESL have announced the next big ticket Manila event. It will be a $250,000 tournament. The tournament will feature eight teams and will be played at the Mall of Asia Arena. You can find more information on the event at masters.gg
