Research topic on esports for future documentary filmmaking

Hey guys, I just need a little help. I'm currently brainstorming for a research topic that I'll be using to do a documentary. Esports have always been my passion and I think I can do great in this documentary, especially it is something that I am passionate and dedicated about. So what are good esports research topics for possible documentary? Mainly in the Philippines? I've already done my first research on the Toxic Culture/Behavior inside Philippine Esports and I did great on that. But now I need mooore topics.
