As a whole esports is downsizing in the Western markets. Dota, CS, and Valorant esports scenes are all roughly plateauing in the Western markets at the moment, which is why Valorant/Counter-Strike are trying to establish themselves in the Chinese market in 2024.

Esports is mainly MOBA games and mobile gaming MOBAs at the moment, apart from CS/Valorant the top FPS games are Fortnite and Apex Legends, which has a sizable Japanese market.
edit: on the topic of Western vs Asian markets, League of Legends set an esports world record with 6.4M Peak Viewers in 2023, while also trying to buy teams out of their North American franchised league
