It exploits peoples need to own, but it doesn't block you from enjoying the game to its fullest other than not owning characters (you can still play them occasionally).

So, like i said, if you at any point want to get your wallet to progress, you are probably playing the game wrong.

You should try ones that are not cash grab - namely genshin and honkai. In case of genshin, if you think you need to spend money, you are doing something wrong. The game locks you out on time basis, not difficulty basis, since its extremely easy with right approach. In case of honkai - dont get into all that "ranked" stuff and you are fine. If you can do that you have really fun single player games, especially genshin. Not to mention FREE. Also, there is some grind, but that is literally nothing compared to amy MMO title.

It really depends on gacha game, I've played a lot both, and i dont mind starting another thanks to those two and healthy approach.
