If you think about it, it does allow the publisher to use less of their "own" money to fill the pool.
This is one of the reasons why esports industry is really going to hit big. I think they are already in the category of multi-billion industry??? But I know, they are already in the multi-million sector. And with the continuous advancement of technology and the young generation who are now into digital tech, no wonder this industry is like a cash cow for so many businesses.
More like in the 8 digits. I was quite shocked when I first saw it on TV, that they are giving away these millions for a "sport" that people play sitting down.
Industry is still gonna grow large, especially with mobile games. Many people don't even own a console and do most of their gaming on their phones and I've already started to see those games hold tournaments.
