There are some fantastic games centered around coins and currency. While not directly about coins, CS:GO has this unique economy with in-game skins that hold significant value. The whole market surrounding CS2 skins feels like a currency in itself, with players buying, selling, and trading these skins. It's an interesting take on digital value that's worth exploring if you're into the idea of virtual economies and collectibles. As for more literal coin-focused games, titles like Super Mario series, Sonic the Hedgehog, or even the classic Coin Dozer offer fun coin-centric gameplay!
