What gacha game are you really invested in the story/lore/characters for whatever reason?

For me, its only HSR even though I play Genshin too, but I'm not as invested in the story. Loved both belobog and penacony arc (even tho penacony isn't even finished), but smth about the story just hits different for me even if it's not perfect. I also feel like some of the dialogues are done really well, esp in Penacony, as dialogues constitute most of the game (eg, Aventurine and Acheron convo in Black hole, Sunday and Astral Express argument about his goals, Acheron and Welt convo). Also cool cutscenes and not too many 2d Overly-nice characters, and MC doesnt feel like an isekai protag number 24757

What do u guys think too?
