Paid gambling as a core mechanic is an automatic pass from me. FOMO manipulation is just gravy on the shit sandwich. It could be the best game ever and I'd still never play it because of how manipulative and greedy the game is. The game with monetization closest to Genshin I've played was LoL and I dropped that ages ago. I've moved on to quality shorter experiences, haven't regretted it for a moment.
There's really not that much of it in the game!! I spent $40, got a handful of well-designed characters with interesting abilities that I could use to play all of the content in the game. Gender distribution seemed 50/50 or only very slightly female, and only a fraction of the characters are overtly sexualized.
