Wuthering Waves is Hella good. Technically it’s an open world gacha game, but I played through all the storyline (the developers will be forever updating the story a la Genshin Impact), and I never spent a dime on it.

Also, I have spent money on Cooking Diary. However, I went about 3 months of daily play before I did, and it was more about me being impatient/telling myself “You got 3 months of daily play, you can drop the devs $4.99”. I’ve played that game just about daily since Memorial Day 2023, and I’ve dropped $5.00 quarterly. There are regularly moments of infinite lives that exceed an hour or two, that it genuinely isn’t necessary. I spend the money more as a “thanks for not making this ducking game contingent on microtransactions, making it good, and maintaining/update it.”
