Yeah and thankfully Nintendo was even pretty good about that with Pokemon Duel and Pokemon Quest. Sure in Pokemon Duel players definitely get a leg up by buying new pieces in advance or whatever for pay, but those pieces are made available to the public later and while it is harder for the most part you can obtain enough jewels to get rarer figures or possibly draw them from boxes. I didn't pay a cent for any of the rare figures I have and I have some of the better ones in the game.

Fate/Grand Order is pretty similar and even though their gacha pool is... very bad, it's not an awful system.
