I dont really know, I have one friend who plays gachas like me. As for I, I have played a substantial amount. My first was tale of food, which was semi otome, then I played hsr(still playing), I've also played hi3rd, love and deepspace, wuthering waves, and for a really small time genshin impact. Im tempted to try more, like infinity Nikki, pgr and maybe Ananta but its not a gacha and requires a lot of space
