it is contested if it is still on top but it is certainly one with a higher female ratio than most, there are newer gatcha games trying to do the same thing but prettier but genshin still seems to have a lot of fujos playing.
it gets content drops every 6 weeks and has various events that are usually mini games and some combat events going at nearly all times where a couple days after one ends a new one starts, for example today there is a minigame where you aim a cannon to fire shots at various common enemies.
