Oh, let's make Bitcoin fun again, shall we? When it comes to games that use Bitcoin as a native currency, there have been some interesting and innovative creations in the crypto gaming space. One standout game that comes to mind is "CryptoKitties."

CryptoKitties took the blockchain world by storm with its adorable digital feline collectibles. Each CryptoKitty was unique and could be bought, sold, and bred using Ethereum (not Bitcoin, but close enough!). People went absolutely meow-nanas for these virtual kitties, with some selling for jaw-dropping prices.

It became a charming mix of virtual pet ownership and investment mania. Who knew that digital cats could be so fascinating? The game definitely brought a dose of fun into the world of cryptocurrencies.

So while not directly using Bitcoin as its currency, CryptoKitties demonstrated how blockchain-based games could capture people's imaginations and add an enjoyable twist to the crypto ecosystem.

Now go forth and may your ventures in both gaming and cryptocurrency bring you joy...and perhaps even a few purr-fectly delightful surprises!
