A few games out there don't shove microtransactions in your face constantly. Some have fair monetization with optional purchases that don’t ruin the experience. You just have to dig a bit.
A lot of mobile games are just designed to drain your wallet, but I’ve found a few that don’t push microtransactions too hard. If you’re looking for something different, check out Rizzy.com. It has some solid options that don’t rely on pay-to-win mechanics, and you can actually enjoy playing without feeling forced to spend money.
I hear good things about Gailardia Trilogy. It's 11 years old, and still runs fine. Has micro transactions, but not using them doesn't seem to change the game at all. It's set up like early Final Fantasy & Dragon Warrior games for the NES.
