Sorry buddy but as much as I like the game, this isn't true in the slightest. The video is extremely misleading because it doesn't account for servers properly. The revenue shown for Alchemy Stars includes JP + KR + Global for one, while for games like Azur Lane, Guardian Tales, etc., their revenue shown is only for the global server.
Azur Lane JP made $6m. Azur Lane Global made $1.5m, for a combined total of $7.5m for JP + Global.
Guardian Tales JP made $18m but they just launched in October. GT global made $1.2m, while KR made $1m. For a combined total of $20.2m for JP + KR + Global. You can search them up yourself, I compiled some of them in an image for easy reference.
Honkai Impact 3rd JP revenue is also being left out. So yeah, HI3 made $3.6m for JP + Global.
The revenue for AS on the other hand is accurate since all of the servers (except for US) use the same client. So $2m from all other servers, and $400k from the US server for $2.4m total.
