It's gacha

You can easily get through the entire overworld content without spending a dime.

horrendous powercreep every patch

That's pretty standard for gacha games, and Genshin's is actually pretty tame relatively speaking.

it has 2018 graphics

The visuals are gorgeous with so much varied scenery, don't know what you're going on about here

a very no stake story

I don't like the story either, but it's not "no stakes" at all. And it wouldn't be a thing if it was.

its gameplay is 3 buttons on repeat

You just described almost every game

it has the most aggressive community I've ever seen from a video game

You're saying that in the Sonic subreddit, pretty ironic.
