What makes YOU play Honkai Star Rail and other Hyv Games?

As stated in the title, what do you look for when playing HSR and by extension, other Hoyoverse Games?

I recently watched a video regarding this topic and it resonated with me: https://www.youtube.com/watch?v=SQGZB3LynjI

TL:DR or Didn't watch the video:

I play Genshin Impact because I like the Elemental Reaction system, enjoy very few character designs and go all in to get them when they appear (e.g Raiden, Arlecchino and Mavuika)

I play Honkai Star Rail mainly for the intense worldbuilding, distinct character designs (even if recycled elements are used) and the gameplay evolution. I specifically had this in mind when pulling for Rappa, as I already had Boothill and Firefly, so there was absolutely no need, yet I wanted her FUN playstyle in my opinion. Powercreep is an issue, but I have accepted that and continued anyways.

I play Zenless Zone Zero for it's characters which yes, may "design bait" with certain elements in plain view, but still has that initial pull, and further enjoy when the character has big numbers and plays well.

Story in ZZZ and HSR has enticed me more so far, though I haven't caught up to Genshin so less to say there.

What about YOU? I'm interested in hearing more about this as I play most games and would like to think I watch multiple CCs with different opinions on all three games.

I want to hear more viewpoints to prevent my own echo-chamber of self-assurance to form.
