Genshin is too greedy. Azure Lane is the way to go. Has more waifus as well, and different artstyle.
Azur Lane seems friendly to your wallet until you're compelled to buy the skins and dock space
. Though yeah it's definitely generous, if you're an early player you likely have every ship in the game... the PR grind, not so much (Okay maybe it's better but I still remember having to grind Roon when only PR1 existed and I had like 1 IB vanguard) Oh and let's not mention needing 50 blueprints for a UR weapon when you get like, 3-4 a week unless you sacrifice your cubes.
I have high hopes for Wuthering Waves since it's open world like Genshin with more interesting mechanics... and Kurogames has a reputation for being pretty F2P friendly with everything being grindable.
It's Essex eating a lemon. She's my spirit animal (I oathed her in 2019 before she became the meme queen)
