I like Honkai Star Rail, it is from the developers of Genshin Impact, but unlike Genshin, it is turned based so the grind is automatic(plus has others quality of life features). So i only have to actively play the actual content.
I think the production values are very high, especially for a mobile game. The story and characters are decent. The english localization(it's a chinese game) is probably the best there is. And finally the music is insane. Hoyoverse is a music company that just happens to make videogames on the side.
What really blew my mind about Star Rail, was the fight against the final boss of the ice planet(second world, after the tutorial one). That was some anime good shit, definitely one of the hypest gaming moments ever and i have played thousands of games. The music they used and how it synced with the gameplay, perfect, absolutely perfect. You can watch this vod of a giant weeb playing the final fight, if you dont care about spoilers or dont intent do play the game(25mins in starts the hype part, though it is worth watching the entire video for context).

The space china world was kinda mediocre but the new Dream/Inception/Las Vegas world is pretty cool. Here is the trailer for this world(this song would have easily won Eurovision this year)

And the trailer for the latest character(least schizo HSR character, persona references, etc)

I guess the most impressive thing about the game is how much content and care has been put into this game. You have pc/console AAA GaS games, which produce very little new seasonal content, no cool trailers, etc. And you have this, till a few years ago random, chinese developer producing high quality content and advertising all the time, they just never miss. And of course now they can do that, they make a billion+ dollars a year but even with Genshin, they are just too good, not just for mobile games but as games.
And it is pretty f2p friendly.
